An old version of the Boss CS-1 compressor with the bypass indicator wired as battery check led. Led is only active with the footswitch pressed down.
Circuit board modified for led indicator as “effect on”.
Here’s a mod for the Morley Power Wah Volume pedal. The mod places the boost as a stand alone circuit, giving the option to toggle it in with an extra stompswitch installed with a LED indicator for effect on. It affects both volume and wah circuit in this configuration.
The channel switching mod to the old Siemens 6 S Ela 2427c installed. The optocouplers circuit board found a place.
Another view, on the left is the input jack, switch for channels and a remote jack for channels.
I removed the guts from the pilot lamp and installed the channel indicating leds in it. We can see the two new pots installed, a clean volume pot and a mids pot.
Another view where you can see the new wiring to the old pilot lamp now acting as channel indicator.

Laney Klipp100 amplifier after modification. The master volume pot was a mod already made. It now holds a switch for channel selection, a 6,3mm jack for remote channel switching and indicating leds for each channel.
Back of the amplifier. Bias pot, bias measuring points , effects loop with send level pot and a gain switch.
Here’s an image with the channel switching circuit board installed using optocouplers .
A closer look at the gain switch mod and the effects loop.
Here’s an image of the bias pot with measuring outlets and the transformer for the channel switching circuit,

A new channel switching circuit board prepared for an old tube amp.
The plan is to fit it in this one.

Since the channel mod was made on the amp it saved a half 12AX7 preamp valve. Decided to use it as gain recovery stage and add an effects loop to the amp.

Adding some optocouplers and making the klipp and the normal input selectable. Using either the switch on the front panel or remotable with a foot switch,
The front panel of the amp with the new hardware added. switching with the remote input.

Turning the Boss DS-1 into something more of an overdrive, giving it a more dynamic response. Changes are made to the transistor booster stage, OP-amp gain stage and the overall frequency respons. Check Thomas Ziden as he gives an somewhat unusual pedal demo.

Got a dead Boss DS-1 on the bench for repair and modification. I just had to replace the fried opamp and it was up and running. I was also told to mod the pedal in anyway I liked. Ever since I made the T-rex Mudhoney 2:nd stage mod the idea has been there to try something similar on a Boss or Ibanez pedal. So here it is on a Boss DS-1 pedal, the feature to choose a latching or momentary bypass.
