What's kind of warranty does these pedals come with? 

As long as I'm building, the pedals have an even-if-you-broke-it warranty. Even if you buy it used, as long as it's fixible, I'll fix it. 

What's with the little controls on the side?

The idea behind having the extra gain controls and such on the side is to allow the pedal to be as flexible as possible, but not have so many easily bumped knobs. The little switches are a bit easier to access than the knobs, and those are just there because it's harder to step on them there. The layout is done the way it is to keep feet away from the switches. 

Can you build me a custom Gnomeratron? 

Probably not, but it doesn't hurt to ask. I get requests for extra features from time to time, but the Gnomeratron is built fairly tight, so modification is tricky, and I have a hard enough time just getting the regular ones out. I'm always open to suggestions, though. 

How is the current Gnomeratron different from older ones? 

The first Gnomeratrons (V1) were more simple and less flexible. They were all hand-wired on perfboard with epoxy coatings for graphics. They lacked the side switches, the gain controls had less range, and there weren't any buffers to help separate the clean and fuzz sides of the pedal. They also had sockets for the diodes so they could be swapped out, but the diodes had to be soldered together back-to-back first. 

V2 Gnomeratrons are all over the place. The circuit was largely the same as V1, but they had extra switches. The switches don't always do the same things, because I was constantly tweaking the circuit at the time. In retrospect, that was a bad move.They also had the epoxy coatings of the V1, but at some point I switched to a better eco-freindly epoxy that seems to age better.

V3 Gnomeratrons are all surface mount, and the circuit grew quite a bit. I added buffers to the ins and outs to prevent the clean and fuzz from interacting as well as separate output boost circuits (the clean and fuzz in V1 & 2 shared an output boost). I simplified the clipping diodes to three options, and moved the "off" position to the side switch. The side switch also allows for an extra "hard" clipping mode. The octave-up got a booster circuit in front to prevent volume drop and increase the circuit's effectiveness. V2 pedals often had switches on the side, but for V3 they were standardized to include the diode modes, oscillation, and clean clipping diodes. The gain controls also have more range, so gain can be turned down much lower than before. I also switched to a scratch-resistant lexan to cover the graphics. 

V3.1 is the current version. The main difference is in the "hard" clipping mode. It allows bass to be clipped, so it's not so boomy. Some trim pots from V3 board were also removed because they were fragile and nobody used them. The booster in front of the octave-up circuit was changed to a bass boost, which makes the octave effect significantly stronger. 

Can you upgrade my old Gnomeratron to have all the features of a new one? 

Unfortunately, probably not, since that would usually mean replacing just about everything. Hit me up with pictures of the inside of your pedal and I'll let you know what I can do. 

Do you make anything but Gnomeratrons? 

Not right now, but I've got a couple things in the works. By "in the works" I mean "in my head," though. We'll see.
