Got this finished off this morning. It's a Ross compressor.
Don't like having the diode standing like that (top right) but I forgot about adding one in for reverse polarity protection until late on. These Schottky diodes have fairly thick leads and seem quite robust, so I'm sure it will be fine. I insulated the inside of the pedal baseplate just incase that lead would have shorted against the casing.
Learnt a couple of lessons today. First, I should probably measure how big the Vero is going to be when complete before I do the hardware layout in future! This very nearly didn't fit and would have been a wasted enclosure. In the end I was lucky that I could snip the corners and the top edge (which was from the edge of a larger Vero board) off with some sharp cutters without affecting the circuit. I did have to move the ground cable from the bottom left to further along the ground rail. As I go along, I will probably end up working out a standard layout for the jacks and switch to maximise the space for the board. Unfortunately, the case I have made for the Klone isn't going to fit. This was 18x18 and the Klone is 21x24 so the jacks would be in the way. Not to worry - The case looks great and I will just use it for another 3 knob overdrive with a smaller footprint. I'll knock up another enclosure for the Klone but I will probably build it first and see how tight it would be in a 1590B - tagboardeffects reckons it will fit, but if it's too tight, wiring it in will be a ball ache, so I may just put it in a BB and be done with it.
Secondly, now that I have pots with the insulating covers and add something to hold the board to the back of them, it adds a couple of mm to the height. This JUST fit, but I didn't have any leeway at all. I did use Command picture strips that I had lying around to stick to the back of the pots and they are probably thicker than standard velcro, but something to bear in mind in future.
Really happy with this. I think I may even make one for myself.
For the resistor I should be ok putting a 330 ohm and 47 ohm in series to give me 377 ohm which should be close enough.
For the cap, could I substitute a 100n or 220n, which are the closest two values I have, or should I just wait and order the correct value? Any idea what effect it will have? It seems to be connected from the ground rail to Tone pot lug 1, the bottom right pin (8?) on the IC and via a 1K resistor to Drive 1.
Cheers
For wahs, I got a cheapie Carlbro (Carlsboro?) thing off ebay a few years ago. It's basically a crybaby shell but chrome and only cost about 20 quid so I was quite happy if it got buggered, and the innards were shit anyway so no loss to the future vintage market!
I put a BYOC board in mine, and drilled for external 9V plus an LED. It's fantastic ally flexible with trimpots for 5 things I can't remember - volume, Q, bass/mid/treble, maybe?? And seeing that second photo again reminds me there's a spare slot for a switchable second inductor. Maybe that's my next project..
Very happy with this one, getting neater each time I build. I've discovered that using @Philtre 's blu tack trick to solder is really helpful and when doing the off board wiring, using the same blob to stick the board upside down just above the enclosure (see below) means you can wire to the pots easily, with minimal length of wire and just flip the board down to mount it on the pots.
Again, the 3.5mm jack socket is in series with the ground from the power supply to enable remote switching from the ctrl out of a pedal switcher.
This one also threw up a couple of challenges where I didn't have the right component values. I was able to chuck a couple of polybox caps in parallel and a couple of resistors in series to get me close enough, but it is challenging to squeeze them in neatly when all these circuits are designed to be as small as possible.
Separate question then, if a tone pot is supposed to be 5k but you use 10k does it actually make the second half of the travel essentially the same as the original tone pot. Therefore the first half from 12 o clock anti clockwise would just continue rolling off high end?
I must get some more pots. 5k must not be very common - I ordered values based on shopping lists from about 20 odd pedal layouts and no 5ks in any of them.
