Members franjo Posted March 19, 2006 Members Share Posted March 19, 2006 dear forumites, i have 2 tonebenderlike circuits here, one is the toneburner from gerneralguitargadgets and the other one is a pedal by spooktone. the toneburner goes great with evry type of germanium tranny, the spooktone is great with thiose hi-gain germaniums. i have gathered some germanium trannies, among them 5 oc140 . sad enough, they only work as 1st tranny in the toneburner, don't work in the 2nd & 3rd position at all and don't do anything in the spooktone. their connection wires to the sockets are fairly thin, but thickening it with tin solder doesn't help either. has anyone an idea?many thanx for any hint franjo Link to comment Share on other sites More sharing options...

On my Fuzz Face clone GE sounds like crap when it is in the first transistor position. Works, but it sounds weak and fizzy. I've been through about 6 different transistors but none have enough gain. My solution was to use a silicon BC109 in Q1 and use the geranium (AC127) in the second stage. Link to comment Share on other sites More sharing options...

Members Narcosynthesis Posted March 25, 2006 Members Share Posted March 25, 2006 one note Germanium = transisterGeranium = flower right, Old transisters vary wildley in gain, so t can be worth buying a few then checking the gain of them on a tester (I know quite a few multimeters have them) as if you have got a set with all fairly low/high/whatever gain they won't be suitedone of hte reasons why old fuzzfaces can be so hit and miss is the differing gain of the transisters, and them just bunging them in and not checking them first David Link to comment Share on other sites More sharing options...
