Maestro PSA phaser and wah Just picked up a couple of old Maestro effects , a PSA phase shifter and a Boomerang wah. The phaser works somewhat, but doesn't sound quite right, there are some trim pots inside but I haven't messed with them yet. The Boomerang wah has signal but very low volume, looks like someone has changed the pot, so maybe wrong value pot and a bad switch? Again any info about schematics etc.. would be appreciated. or know anyone close to Memphis TN who does effects repairs reasonably? Thanks! |

Frank E | Here's a link for the schematic for the Maestro Boomerang Wah, I have a couple of them myself and they sound awesome when they work correctly. I would check the 1uf electrolytic caps, they're probaly the originals which would make them about 30 yrs old. Hope this helps. Frank http://www1.korksoft.com/~schem/veffects/mboomer2.pdf |
