I agree with Travis - sounds like a Superfuzz to me.
Build one Gilberto, you won't regret it. However I woyld use a PCB like this one from Fuzzdog in the UK:

Use this PCB and you can easily fit it in a 1590B. I have used this PCB a couple of time now, and compared to the vero, it is an easy build.
