Thank you for sharing all of this, it has helped me immensely! The truth is, I did not really understand all this stuff ;) What I did is accept facts I read, for example that mu-amps are vertically stacked and are self-biasing, or that you might have to scale tone stacks according to impedance...

So can somebody please tell me if I understood right, because this is hard to grasp for me: Mu-amp in general: JFET 1 acts as an active load for JFET 2 -> source 2 to drain 1 SRPP: JFET 1 gate is directly connected to voltage divider to bias (DLS II) Mu-amp: JFET 1 gate is directly connected...

Hahaha, thank you, I'm glad it's not just me. I just was feeling a little bit bad about the little circles I created by not understanding as fast a people answered ;) It is fun, especially as I never cared for the internals and function of circuits, I only wanted tu assemble and then play them...

Happened to me several times now where I read through your replies, try to understand everything, and out of that new questions evolve that I eventually ask here, only to realize afterwards that the questions had already been answered and I just didn't get it yet xD Part of the process, I guess...

I just looked at the docs for the DLS Mk. I and the DLS Mk. II to try and understand this better. If I'm reading the schematics right, it looks like they both use mu-amp pairs (like Q2/Q3 and Q4/Q5 on both versions), while the Mk. III uses a different design. This brings up another question...

Hey everyone, Thank you so much for all the help. I might not be new to building pedals, but I'm definitely new to trying to understand the function of a circuit and modding it to taste. So I'm really glad people are willing to help me and share their knowledge. I realize I'm just at the...

Thank you! 1. This makes sense, but I thought the Hi Bass input would be the way to go, so I don't loose signal and have the full frequency range. Did you commonly use the Lo-input with those amps or did I misundersand the schematic and your answer? The High bass input resistance is 68k, isn't...

@Locrian99 I am just being specific for no good reason at this point ;) I'm done with the little mod now. In the end, I decided to change the Super Lead side to the Sunn T specs because the globally shared values seemed a bit too off for the Super Lead. I also thought about using the trims from...

Hey, I was away for a bit, so sorry for the late reply. I had a proper look at the Super Trouper docs and decided change a few component values on the Super Bass side of the Catalinbread DLS since it is very close to the Supergroup anyways. Also, thanks @ICTRock if that was an offer to send...

Thanks for the heads-up, and sorry if I missed something, it’s getting late here

That is some nice insight!

Thanks for that resource! You are right, that would be catchier, but actually I want to built a preamp in the ballpark of those vintage amps and since I found out the Supergroup is very very close and i am a Sabbath fan I want to build the Laney ;)

Alright, that’s kind of what I want to do – identify the component values in a pedal that differ from the Supergroup and change them. Not looking to recreate the whole amp, just get in the ballpark with a preamp-style circuit. Thanks for the example! I actually saw it before but stopped reading...

Thank you, that’s interesting! I do know about the Catalinbread Sabbra Cadabra – cool pedal, but I always felt the control layout was a bit limited in terms of flexibility. Also, I thought it wasn’t an actual Supergroup preamp circuit, but more of a soundalike design – kind of like how the...

Thanks for the reply, really appreciate it! Checked out the Laney LA30BL – that thing's definitely on my wishlist once the budget allows. Hope your enjoy yours! I read that with older Laneys and Oranges, the power section – including the transformers – had a noticeable influence on the tone...
