I am in the process of finishing a 5E3 build, but know already from clips that the stock form will be too bassy for the LP's - which I play most of all. But I do play strats and Teles quite often - as well as having a Jag and JM too. A fix for the farty bass seems to be replacing the 1uF coupling caps are going for a lower value - but for a strat say it sounds great with the higher values. What I'm most interested in is knowing if with a DPDT on,on,on switch or similar if you could have a switching operation for say the normal channel coupling cap. Where you could have 2 caps as an: A, B, A+B possibility. Would the switching action have popping issues.....what (if any) grounding would be needed for the housing??
