I've been thinking about this concept for a while now and mulling it over in my mind... I hate to say it but I really don't think a Rat would make good sorbet.
My mum always said to me "Son, if you're going to have asymmetrical clipping by having different Vf between diodes you might as well go all the way". She was a wise woman, my mum.
Really nice job! It's a really good circuit. The one thing which spoilt it for me a bit was C5. It makes the sound a bit fuzzier than my actual Marshalls. I would definitely recommend experimenting with smaller values there. In the end I put a bass pot in mine which goes from 220nF to 22µF...
Uncle Doug's is probably the best Tolexing video I have seen. Tolexing cabs gets easier with practise! And using actual Tolex makes the job easier too. A lot of vinyls designed for upholstery are too thick and makes covering a cab much harder than it needs to be. I also prefer to use the smelly...
Looking at the PPCB schematic the 0ohm resistor and Presence pot replace the 47R resistor to the 2µ2 cap. So disconnect the pot and jumper (0ohm resistor) and solder a 47R resistor between the positive side of the 2µ2 cap and pin 2 of the IC. You could connect it at the Distortion pot's lug 2 or...
Just to be clear, the Bee Sting is not a One Control Silver Bee. It is a fairly substantially modified Silver Bee. The Silver Bee surprised me because it sounds really good and a bit clearer than a Honey Bee. The Bee Sting is clearer still. Part of that is from replacing a single opamp chip and...
