UPDATE - I no longer recommend doing this mod, it can have some nasty (thumping) results. A new phototutorial has been made here: viewtopic.php?t=1578Click here to listen to a demo.
One day I opened up a Small Clone to do a few mods to it, and somehow managed to make this thing into a Tremolo. It's quite an easy mod, and chorus and tremolo sound brilliant together, so let's get started, shall we?
Before we get started, here's the necessary "If you break your Small Clone, it's not my fault". You can always mess up, and I try to make this as safe for you as possible, but if your small clone stops working, it's not my fault. I'll help you fix it, but I'm not going to be held responsible.
Here we have the parts that we need. You only need the pot and knob if you've already done the super-high speed mod, available at Moosapotamus's webpage
. On my personal small clone, I did all of the mods at his site (except for the stereo one). For this particular pedal I'm modding today, he only wanted the tremolo mod, so I'm not going to need the pot. Basically, the pot serves as a "ramp" knob. When there's no resistor there, it thumps at lower speeds, but with a resistor there on the super speed, the ramp is too fast and it cancels itself out. So, basically, if you're going to do the super speed mod as well, you need the 1k pot instead of the 1k resistor, otherwise, just use a 1k resistor.
Here we have the thing opened up. Note that I undid all of the nuts from it so that I could mode the circuit board away from the case-this is a good safety procedure for drilling. Yeah, just do it, you'll be super mad if you drill into your pedal and tear a hole through the MN3207.
These are the 2 points you're going to want to connect. Shown here we have the 1k resistor, instead of the pot, because there's no high speed mod. If you have already done the high speed mod, just put a 1k pot there instead. Be sure to put this resistor here, otherwise it will thump unpleasantly. Don't forget to try this thing out to make sure it works BEFORE YOU DRILL.
Here's how I mounted the switch. I used a super sub mini ultra small super tiny mega small mini SPST, so I could fit it in there with all the components. If you're using a bigger one, try putting it somewhere else, and check to make sure it will fit there BEFORE you drill.
And here's the finished product. I put the switch right in the middle of the "O". How cute, eh?
