3x3x3 Perfect Guitar Rig

I’ve seen a couple of recent blog posts and forum threads talking about top lists of classic guitars, amps and pedals, and at the same time, in the same places, people talking about uncluttering their rigs. That set me thinking about what my ideal rig would be – restricting myself to three amps, three guitars and three pedals. I’m also going to restrict myself to freely available gear; no customs, boutique or limited numbers stuff. So here are mine:

Guitars

Gretsch G6120DSV
dsv12

Fender Telecaster Standard

Gibson Les Paul Goldtop 56 Reissue

Amps

Fender Priceton Reverb Recording

Ampmaker SE5a Brass Plaque Patina

Since the silverface Twin Reverb arrived a few weeks ago I’ve been neglecting my self-built Ampmaker SE5a. Today I gave it a bit of a clean and cracked out the Brasso to give the etched plaque some TLC. I’m really pleased with how it turned out and the way it is starting to build up a patina. And boy does this amp sound great with the Gretsch’s DynaSonics. It doesn’t have the Twin’s crisp shimmer but it I love the punchy, rounded, but not overwhelming mids.

Fender Twin with 12AT7 in the preamp

Day 3 with the Twin Reverb and I managed to get a couple of hours to explore further. I tried swapping the 12AX7 tube in V2 (the Vibrato channel) for a 12AT7. It’s a fairly subtle change. It means that the preamp doesn’t slip into overdrive as easily. I’ll leave it in for now but no doubt I’ll be going back to the 12AX7 before too long.

I also got chance to experiment with my collection of pedals. As many of others have already documented, the Twin Reverb is a great amp with pedals. I had most fun with this stripped down setup. Perfect for rockabilly twang. The gem of these is Alfie’s Blue Alpaca. It just makes the amp sing.

Right to left they are: Behringer DC9 Compressor, Nocturne Brain Seltzer, Alfalfasprout Custom Shop Blue Alpaca (inspired by the Way Huge Red Llama) and finally a DigiTech DigiDelay for a bit of slapback.

All of this was with my Telecaster. I’m really looking forward to 12th Jan when I’ll have my Gretsch 6120DSV back home.

Twin Reverb gets a “spring” clean

The Twin Reverb, whilst sounding remarkably clean was looking anything but. Time for a good clean.

The tolex is quite badly knocked about in places so I wanted to make sure it didn’t get too wet.

I dismantled everything, removing the valves and the amp chassis too. While it was apart I took pictures of the valve chart and serial number for future reference.

I gather from this site that the “F09” denotes 1979-80.

In small sections with slightly soapy water and a firm nail brush I’d work in small circles, wipe dry and repeat a couple of times until all the ingrained dirt had lifted.

Here’s a before and after of the top.

Not a massive difference on first appearance until you look at what it did to the water and detergent mix.

The reverb bag was particularly dirty but cleaned up very nicely.

There had been an intermittent problem with the reverb disappearing which I’d traced to a dodgy connection on RCA Phono plug on the return from the reverb tank. I replaced the whole cable with one I had in my parts drawer.

The interior of the chassis itself was pretty clean but I gave it a light dusting and checked everything looked OK.

I put everything back together, returned the valves to their original position and checked that everything worked. Now the outside is almost as clean and sparkly as the sounds it makes. The valves fitted all look pretty recent. They’re Electro-Harmonix in the power tubes and a full set of JJs for the preamp.

One last job for today was to make myself a “fake” footswitch for the tremolo. As standard you need to have the footswitch plugged in for the tremolo to operate, whereas by default the reverb is on. I like to keep the tremolo on all the time but at a very low, almost imperceptible level. Rather than connecting up the footswitch and leaving it rattling about in the cavity at the back, I simply took an old RCA Phono plug, soldered the centre to the shield and hey presto, full-time tremolo with no footswitch.

Next job will be to experiment with the preamp tubes. I’ve got a spare 12AT7 knocking about and this can be used in place of the 12AX7 in V1 or V2 for the Normal and Vibrato channels, respectively, dropping the gain slightly, giving even more clean headroom (if such a thing is possible).

Another interesting idea I want to try out is that, because unlike most amps, the two channels are totally independent and can be used at the same time, you can take the return from the reverb tank and feed it directly into the normal channel, allowing you to control the volume and EQ independently of the dry signal. All that is required is an RCA Phone to 1/4″ adapter.

New Amp Day

The Behringer GM110 has headed off to a new home (a gift for an ampless friend) and so I was in the market for a replacement. I’ve spent a while enviously and forlornly looking at classic Fender amps. Over the last year everything I’ve been looking for has been summed up by that shimmering, sparkling Fender clean sound. In Nashville earlier this year I spent a very happy afternoon with a Princeton Reverb and I was sold and have been keeping my eyes peeled for one at a reasonable price. Unfortunately they rarely appear for sale, and when they do they’re far from reasonably priced.

I’d always assumed that the big boy of the Fender range was out of my price range and then I stumbled across a silver-face Fender Twin Reverb on eBay at around half the price of a Princeton. Deal done and the new baby arrived at home this afternoon. It is one of the late 70s models which is not loved by the cognoscenti. The downside is that it is 135 watts! I’ve got plenty of headroom to play with! Everything is working fine but it is overdue some TLC. It’ll get a clean and fettle over the next few days. To say I’m happy with it would be something of an understatement. In fact, let’s leave it there. I’ve got a new toy to play with. Ciao.

Behringer GM110 Review

I’ve now had three weeks with my humble travel combo. It must be review time. First a summary of the amp and it’s key features:

  • 30 watt (RMS) solid-state 1×10″ combo,
  • Analog modelling with three amp sims, three speaker sims and three gain types,
  • 3 band eq (bass, middle, treble), drive and master volume,
  • Connections for FX Loop, external speaker, headphones and XLR balanced output.

I’ve been using the amp with my Gretsch G6120-DSV (featuring the single coil DynaSonics if that matters to you) through a cut down set of pedals (Behringer DC9 Compressor, Behringer UT100 Tremolo, Digitech DigiDelay, Boss RV-5 Reverb).

Aesthetics and build
Very clean and neat and has a feel of quality about it. The combination of black tolex, silver grille cloth, chrome corners, polished metal chassis and chickenhead knobs all look the part. It feels substantial and well put together but not overly heavy. Overall, much better than I would expect for such a modest piece of kit.

Gain, Drive and Master Volume
The switchable gain type, along with the drive control, gives a phenomenally broad range from ultra-clean to ultra-dirty. Unfortunately, once things turn dirty some problems with the amp become apparent. At lower volumes the distortion introduces an unpleasant and harsh high pitched fizz. Take the pedals away from the chain and this disappears. I’d always thought that the phrase “takes pedals well” was a load of BS, but I;ve finally found an amp that doesn’t. It could be my power supply that is causing the problems but if you;re considering a GM110 make sure you test it with your own gear. Caveat Emptor and all that.

Amp sims
“Tweed” sounds great but is quiet compared to the other sims. Even at the the highest levels of gain/drive there is no more than the faintest crunch. This is perfect for me and the amp does a decent job of mimicking the classic Fender sound. If the EQ is flat then it is very, very bass heavy and does need correction. Thankfully the EQ section is up to the job. The “British” and “California” sims don’t quite hit the mark for me. When clean, they both lack character and are rather dull and uninspiring. I suspect they’re both tailored for higher gain settings. I won’t be using these much.

Speaker sims
The choice of “US”, “UK” and “Flat” is, to a certain extent, moot. The differences between them are very subtle. The difference is audible when you flick back and forth between them, but only just.

EQ
Very, very flexible and a good job too because this is an amp that needs the EQ tweaked to get the best out of it. Some amps sound good on any EQ setting. My Ampmaker SE-5a is a great example of that. You can fiddle with the EQ to change the tone but it is practically impossible to find something that sounds crap. The GM110 isn’t one of those amps. Spend a bit of time with it though and this is no problem – I can conjure up the sounds I want, it just takes a little bit more time and care.

Summary
The GM110 very closely matches my needs; a good-looking, neat and compact combo that can pair up well with my Gretsch and give me those shimmering Fender tones at low to medium volumes. It’ll fit in the boot of my MX5 and doesn’t break the back or bank. If I had paid full retail price I’d be satisfied. Thankfully I paid a lot less and that makes me a very happy bunny indeed.
