Currently using 2N5088's. I was wondering what you've used instead and what the results were? Thanks.
Just ordered 2n5089s and 2N5133's and currently have 2N5088. I'll let you know the difference.
I would be curious how lower gain transistors work in the BMP. I know this may sound like crazy talk, but I've always felt that the BMP gets a little mushy at high gain settings. Has anyone tried this?

I was just cranking up the volume some on an OS Comp>BMP, mushing out real nice...lol.
I tried using 2n3904's, was noisy and lower gain...
BCxxx's [around 200-300 hfe]...pretty cool tone.
Ge's, I don't think they were gainy enough, I still have on in there though as Q2.
I ended up for the most part liking best with the HG/LN transistors, 2n5089, MPSA18, but couldn't tell much/any difference between the HG and the medium high gain 5088's...it ends up with 2x 2n5088, a 5089 and a Ge. still fairly noisy, but that mush is worth the stompoffs to eliminate the noise level with Comp>BMP set high gain.
BC109's... ;D
Fairchild 5089's for me :D
High gain & mush ..... that's the BM !!
MM.
I tried several but the lower the Hfe became the more useless the sound was............ (to my ears)
5088 for me; I have same 89 laying around and will pop em in today to see if I like em
I have built several and had good results with BC184C and BC549C. The 2N5088s I tried gave a strange 'after' sound.

............tried the 2N5089 and 2N5133 in lieu of the current 2N5088. I pretty much want this thing with gain maxed for that saturated Pumpkins tone. With this much gain, I didn't notice a big difference and since the 2N5133's were a bit less noisy, I went with those. My next curiosity is what diode type? I think I have Si in there now but don't have any Ge's to try.
Were your 2n5133s the button or the can type? I've never got my hands on the cans, but I really like the button 5133s I've gotten ahold of and used. They seem to have more grit and snarl than 5088...
The button ones (from SmallBear). Yeah, it did seem like they were a little less refined with me as well.
Oh, and you mentioned diodes. I've found that using one 1n4141 and one 1n34a in the first clipping stage and 2 4148 in the second make for a very rich and somewhat octavey flavor.
