THAT4301 Substitute?

The 4305 works great but requires BJT opamps. You cannot use jfet opamps, like TL072. The chiclet linked above and also available at pedalpcb work fine. They use NJM8080 or NJM8068 opamps. This link describes the difference between them.

I've made a custom PCB for the muzzle using the SMT components and it works great. The goal of this was to make it as compact as possible for a combo pedal that will be the core of my pedal board (Muzzle, Mini-spark, Prince of Tone, AMT LA2 M2 and C2).

This is what the combo pedal looks like... Muzzle is upper right. Still waiting on a PCB for the channel switching in the middle.

Hi. Are you able to share some information about how you made the custom pcb for the muzzle?

I’m interested in doing the same myself since Pedal pcb is out.

I used Kicad to enter the schematic and layout the PCB and sent it off to PCBWay. It's shared there...

Probably a dumb question, but if I select 1 PCB build on PCB say and it says something about adding 5 to the cart...am I going to get 1 populated board or 5?

I've obviously not used pcbway before so please excuse me.

Are they able to pull directly from your parts list and populate all that stuff without me telling them to? I see an option for me to supply the parts but if they can find them for me obviously that's better.

Can you tell me what is going on here? This pot seems to have 4 connections?

Looks like it makes sure the pot case is grounded. The case usually makes contact with the metal enclosure when screwed into place, but you would want to make sure that the part of the enclosure touching the pot casing was bare metal and not painted.
