Original thread and schematic available on the FSB forum here.
Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter

Nice layout Alex!
ReplyDeleteBeen looking for something to put into a 6 knob 125B, this looks like a winner.
This is one i been wanting to check out and the Baja EVH5150.Thank you Alex,your layouts always look great to me.
ReplyDeleteBe careful if you build this: layout is actually 23 x 22. It's been corrected.
DeleteI believe the schematic has the cap value coming off the 2sk117 source at 1u.
ReplyDeleteThanks Michael. I've used the Bassman layout and forgot to change the value.
DeleteThanks Alex for the headsup on the correction.I always save all the new vero layouts as soon as they are posted then watch for any corrections then resave those as i delete the older ones.
ReplyDeleteI guess I can't say the layout is officially verified, as I had altered mine a bit (additional power supply filtering and moved things around to accommodate strain relief holes), but considering my layout started off as Alex's, I'm sure it's good to go.
ReplyDeleteInitial test sounded pretty good. Seems to only have a mild level of crunch though with the Gain cranked and Presence turned up a good bit. Increases a bit when digging in, I guess like an older tube amp.
Most likely needs to be pushed by another boost or OD, although I didn't get a chance to check that out yet.
Having never heard a '59 in person, I can only assume this is a faithful representation. Sounds good though.
I had used LEDs for the final clipping, but one of them barely lights up with everything dimed, 1n4148s are probably the better choice here. I'll swap them out tonight and check it out with another boost in front. I may also tweak the 2k7 feedback resistor as Frank mentioned over at FSB.
Again, thanks for another great layout Alex!
Ok, the 1n4148s at the end definitely sound better than the LEDs I had tried.
DeleteIncreasing The feedback resistor up to about 5k1 sounded ok, but I settled back on the 2k7. Probably not worth a switching option.
A boost in front livens things up a bit as expected. Might acually be a good pedal platform for testing treble and germanium boosts.
IMO, sounds decent for rhythm as is, then kick in a boost for the leads.
Looks like this might be the one to get me back into building pedals after a long time of quietness.
ReplyDeleteGREAT!
Hey Doron, built a Kallas modded fuzzrite after hearing your Green Spirit page! Did you ever build this '59 and was it cool?
DeleteThanks for sharing, nice post! Post really provice useful information!

Is there a substitute to the 2sk117? Can I use a J201?
ReplyDeleteVery good one ! I found the treble pot to be quite subtle. Is it something ok ? If yes ,Is there a way to make it darker at min settings and brighter at max ?
ReplyDeleteI have doubts where is the mid 3 -> bass 1? congratulations for the layout, I'll do soon.
ReplyDeleteHey Zey, Thr Mid 3 connects to Bass 1. There is no connection the the board, thr are just connected together.
ReplyDeletethank you very much!
