Posted a "mangler thoughts"-thread under tech help a couple of weeks ago where is presented my Idea about toggle-switches for both transistors and the trimpot in a mangler.. Had some time to test my idea and I'm happy to say it sure will work! I tested it with CV112's and BC109. There were not that much popping when I switched between the two either!

Both bias-pots works fine but the main problem now will bee to source a couple of good BC108 or BC109 that have good gains or whatever (don't really understand all that... but I'm learning).
Will post more pics when I'm ready. Haven't drilled holes for jacks, DC and possibly a led yet. Will probably wait to finish this one until I get some shielded cable I just bought from eBay.
