The standard switches soldered into the PCB are DPDT which are no good for true bypass with LEDs. 3DPT is whats needed.
A little bit of care is needed, the 2nd switch was much easier to fit once I had figured out how to do it by trial and error on the A/B switch.
Knowing my luck, Radial will probably announce the improved Mk2 BigShot
with LEDs next week
I would definitely do it again if needed, a big improvement in functionality for me.
======================================
Lifted from the other A/B thread -
Well the 3PDTs arrived today! Fast service from http://pedalparts.co.uk/. The A/B side is in - blue for A, yellow for B. Working fine - no pops or crackles.
This is not for the faint hearted, you need to do work on the PCB...
warranty will be invalid.
I will tackle the Y section tomorrow. Red for both.
It's impossible to photograph the inside as it is all crammed in the space above the PCB. Enough space behind for the 9v cell.
But I can describe what I did.
Removed the PCB, desoldered the 6 poles of the A/B switch, some of the tiny eyelets came loose so I replaced them with normal 1/8" eyelets.
Drilled the casing for the LEDs, fitted these with resistors and sealed these in shrink tube.
I added 1.5" ptfe flying leads to the PCB and soldered in the 3DPDT, having numbered the wires the same as the old switch. These wires fold down under the switch.
9v battery is switched via the LEDs ground through the input Cliff jack, ring and sleeve.
It is a pretty tricky job and space is tight but I have what I wanted.
Shame Radial don't throw $1 worth of LEDs and $5 of switches at this excellent switcher. Oh well ...
I'll put up some pics of the LEDs in action when I finish tomorrow.
