Thought I'd relay my experience building the Matchbox kit here in case anyone else tries to build one of the OLC kits themselves. All in all the pedal turned out OK. If you order a kit online and pay with paypal make sure you also email OLC so they know to send the kit out. They don't have anything outside of paypal to confirm that they received your order, so when Mark replies back that'll give you a little piece of mind. A parts sourcing problem delayed my kit from shipping for about 1 1/2 weeks. When it did arrive it was missing two trimmers and caps which took about another week to arrive. So about 3 weeks after my order I had all the parts needed to finalize building the pedal. All or part of the instructions were written by a "Beavis" and there are some things to watch out for here. The BOM lists a coulple of different values for some items than is provided and shown in the assembly instructions that come later. Turns out the BOM is wrong and the part and assembly instructions are right. Populating the board is pretty straight forward and I didn't have any problems once I had all the right parts. Might be nice if the terminals to go to the off-board wiring were a little bit bigger holes. You'll see why next... Wiring up the board to the jacks, pots, and switches is where the real problems start. They start with having you wire up the power jack, in/out jacks, and stomp switch. Problem with that is the pots have to get wired up underneath the jacks, so you'll have to remove the jacks after they're wired to be able to wire the pots. Not such a big deal until when you notice that the instructions have the pots in the opposite order from where they actually fit in the pedal case! Now you'll have to redo your wiring because it makes more sense to orient the PCB 180 degrees for the correct pot placement, moving all of the terminals to the jacks and switch. I lost at least 2 hours to that one and needed more wire than was provided to fix things back up neatly. Finally everything was wired up so I hooked up a guitar, amp, and battery to get rockin'! But, no LED or sound when the pedal was switched on. Turns out that the provided TRS jack for the input was not connecting the ring to ground when a cable was inserted. I pulled the input jack and tested it alone with a cable to confirm this. Replaced both in and out jacks with some from Radio Shack and the pedal fired up finally. But wait, there's still some problems. The Volume, and Cut knobs are working backwards from the description on the website. For some reason the Master was OK and they mention in a note that the Tone supposed to be opposite the ROG original in this kit. Easy enough to switch the Volume and Cut wires. Now the pedal seems to work as originally intended - the tapers on those 2 pots make a difference to the ease of dialing in a workable tone. Good news is that OLC is going to be updating the instructions for the Matchbox and they made good on sending replacement parts and keeping up communication. Hopefully they'll go through their other kits and double check the wiring because I'd like to build some more this year. Probably the Supro and Prof Tweed and maybe the English Channel. I do think it may have been worth it to allow OLC to build the pedal for me because they put a nice finish on the case. I've probably got about 8 hours of labor into this Matchbox and at one point became very frustrated (the wiring and bad jack part). How does it sound? Well, a little thinner than I'd hoped. I just traded away a Matchless Hotbox to a fellow TGP'er a couple of weeks before and I was hoping the Matchbox would be an acceptable, smaller replacement. But, it is not. It does have a decent sound of it's own and if I use a pedal as a bass booster in front of the Matchbox it sounds pretty good (using a HAO Sole Pressure). If I get a chance in the next couple of weeks I'll try to put some demo clips up on youtube.
