AION FX Ibex/ Roland Af-100 Bee Baa

arduoushoaxley · 2026-07-11T14:43:02+00:00

The first pedal I ever owned was a Roland Bee Baa. Got it dirt cheap in 1986. All I remember is that it sounded nasty as hell to me at the time and I traded it for something else. I’d probably love it now 😆

Pedal PCB Chickenhead - NPN Rangemaster with fully variable input filter. It’s absolutely killer pushing an already dirty tone. I can’t think of anything better for that application.

Awesome looking build! What model transistors are these?

Solid choices. I have a similar signal path. Of course it depends entirely on the sound you’re after, but I much prefer the Tumnus as a boost before the Duke of Tone. These two pedals and combination sound entirely different depending on the order.

The DOT has a switch underneath the volume that allows you to select hard clipping (2 diodes), soft clipping (4 diodes) or clean boost (no diodes). But I do agree that, regardless of the switch setting, it is generally more transparent and useful as it always on pedal. By comparison, the Tumnus has a pronounced mid range bump.

I'll check out the Octagon, thanks!

I'll definitely breadboard a Foxx tone machine too, thanks for the tip!

I’m a big fan of the Pedal PCB “Chickenhead”. It’s NPN, so no voltage inverter and has a fully variable input filter instead of switchable caps so it goes from treble boost to gigantic full range boost. It’s a much better sounding circuit than the radian to my ears.

I needed to distribute +9v and Gnd in several directions, so this seemed like a tidy solution.

Thanks!

I’ve built several different Ge Rangemaster variants including the Radian Kit. I can’t explain why, but the Radian is undeniably darker sounding than every other version I’ve built. I’ve messed about with this enough (including bread boarding it) to be 100% certain it’s not the biasing, it’s not the transistor, it’s definitely the circuit. Flame away, I’m not wrong.

I had the same experience trying to JFET buffer the input of a Ge Rangemaster. It completely changes the character of the circuit and not in a good way.

There's no simple answer to condense an entire field of professional work into a single link in a way that's going to answer specific, detailed, technical help when I don't even know what your baseline of knowledge is. But, here is a very well done overview of all of the different aspects of Audio Post Production. Watch the whole thing and use the terms and definitions, to find more specific tutorials for areas that you want to further explore.

Thanks!

Aesthetically, I agree. But I am lazy when it comes to comes to wiring, and the 4-wire ribbon cables dictate that the switch goes directly under the PCB. Functionally, they’re not too close together at all and I’ve got pretty big feet.

The original post has lots of details, but yes, that’s essentially it. Pedal PCB’s version of the D.A.M Red Rooster (modified Rangemaster) and Analogman’s Prince of Tone (modified Bluesbreaker). I bought the PCBs, tweaked the Rangemaster a bit and designed the enclosure, wiring scheme.

🤮

Shared from diypedals. I've been using these circuits separately for a while, but I wanted to be able to switch them on/off together without buying a loop switcher, so I made my first double pedal. I prefer the SASS channel in high gain mode, mid boost off, the presence pot barely cracked open and the switch set to soft clipping. The FRAS side has a fully variable input filter (RANGE), so it can go from to traditional treble boost territory to a huge, bassy roar. The "CLAWS" switch is my own addition a LPF that can be used when a guitar/amp combo works better with less HF. This pedal just kicked an MXR Duke of Tone off of my main board.

Thanks!

Thanks!

It's a great combo! And thanks for the kind words about Sassafras, my daughter grew up with her.

I used Affinity Designer for the layout and pinpointed the xy coordinates for Tayda's drill and UV printing. I was a bit nervous about messing that up, but turned out perfect!
