Reverb Mate, Sole Mate , spring reverb

Brand new out of the box and the footswitch is broken. Owner wants me to replace the switch rather than returning to the importers for a replacement. While in there try and sort out what apparently is an age-old problem with such external reverb boxes. Set guitar , amp and reverb for clean and then excess gain when changing to "dirty" ch. He does not use the second footsw so I'm thinking of using that to switch in a preset over some gain setting part of the cct - anyone been here before? Hiding to nothing? Existing user pots are output level and dwell but not mix. LED next to that sw already there to indicate the gain state if I alteM

Reverbamate that should be by Van Amps Sw marked with logo YIS in a diamond on one side and RoHS on the other - say no more. Will have to break into this sw to see what this new to me, presumably generic, RoHS problem is.

Why not just simplify things immensely and swap the second footswitch, that is not used, for the broken one.

I'm replacing the used one with a different make as both show 2 to 4 ohms on some connections. A few ohms variation on a preset of a few k probably would not matter for a clean/dirty gain switch. There is obviously a duff batch of these YIS ones, will remove and open up one today

Probably a generic failing of "X wing" format of footswitch rather than RoHS. Because of the X format the contact surface to the tipping contact is a point rather than a line so it punctures through the silver? plating of the tipping contact, into ther base metal. Then an irregular surface to trap contamination etc inside the pit . Regular format like standard toggle sw would have the fixed contacts appearing as a line because orthogonal to the casing rather than 45 degree set. By X wing I mean this external appearance

Who designs these things? probably graphic artists or media consultants because the X appearance looks good.

Got back to the over-overdrive problem. Send side of the springline easily driven into clipping , I will try reducing the gain of the send side amp and increase the gain of the receive side and add some mechanical/acoustic decoupling to the tank

No longer clipping on large signal input. Originally the tank held by 4 large bolts , large enough to hold a 500W transformer, not a 2 ounce reverb tank. Decoupled with 4 small bolts passing thru 4 of those floppy rubber CD optical deck vibration decouplers, so no direct metal coupling now between tank and case. Much the same throughput so hopefully a mod repeatable in this generic fault area of external reverb boxes.
