So I’ve been tinkering with the aft pre amp (I’ve posted yesterday on the wrong workbench haha) the circuit calls for an oc139 ge transistor and I don’t have one of those so I’ve only been swapping out the transistor while maintaining that 470r in place of r5 and here’s my thoughts on what a couple of these little guys do:
2n5088 - this was the first one I tried I immediately fell in love with this sound so much in fact it’s what made me buy the circuit. There is ALOT of boost on ready and will easily get you into overdrive territory.
2n5089 - the one I ultimately am going to use in the final build. This screams even louder while still maintaining the character of your amp and guitar. This thing is my favorite sounding it’s what I currently have installed in the pic. Take my word for it I think they could’ve went this route in the original and still made a killer pedal!
Mpsa18 - WAYYYYYY TOOOOO LOUDDDD
This thing not only makes you wish you wore ear plugs but it drives so hard you lose character in the sound of your amp. Some people might find this suitable but for me it’s just to much……did someone call my name?……
2n3906 - pathetic…….
2n3904 - sounds really really good but I feel it’s a little darker than both the 5088 and 5089. Something that ultimately made me lose interest as I was already fixated on what the 2n5088 and 2n5089 sounded like.
