TRansistor replacements for Hogs Foot BAss Booster
Can anyone tell me a suitable replacement for 2n5133's whicih the hog's foot bass booster schematic requires ?  
 
Would any NPN to92 transistor work (such as mpsa18 or 2n3906)  
 
 
 
THANX

Following "R.G. Keen's Law of Substitution", you might try the 2N5088 and see how that works......

2n3906 is a PNP the 2n3904 is a npn. 2n3904 should work

Ok thanx, yah 2n3904 is what i meant, typo...would mpsa18 work also?

Any high gain NPN should work fine. The unit's not designed as a distortion device, just a gentle booster. Overdrive it with another hot signal, and you may start to notice differences between transistors. FWIW I always use 2N5089s for this sort of thing.

Is it possible to replace the i/o caps to a larger value to get more bass out of the unit?

Only if the stock values are limiting the bass response, which would seem unlikely in a bass booster, wouldn't it?
