Yesterday I built a board and it has some issues. parts PT1, Voodoo 4x4, RMC, Klon Clone, Neo Mini Vent , Fulltone Mini vibe and a DD6. I had an El capistan and a soul bender but then seemed to make things worse. order So The guitar goes to the Wah then to a junction box with 3 loops and out to the amp. on loop one was the Clone and the Soul bender, 2 was the Vibe and Vent on 3 I had a El capistan and a DD6. The hiss was so bad I got rid of the EL Cap, getting rid of the SB and rewiring seemed to quiet it down. problem Now here is the problem. When I switch on the wah the noise level jumps up, lots of hiss almost as if the a cable was lying on the ground. As your working the wah it seems to go down a bit. Next issue: the Vibe makes a high pitched whirling sound in time with the pulse, but only dose this when the clone is engaged, on a separate loop. The volume of the amp accentuates these issue but they are there at any level . The loop is a DIY project that never gave me any trouble when I had a piece of wood and used Warts with a power strip.
