Something Special

Project: Prism (Boss FA-1 FET Amp)

Build description

This is a very transparent boost with a Bass & Treble EQ. I see why the original FA-1 goes for $500. I Used the HA1457W OpAmps. Just be sure to use C13 & C14 if you use these ICs. I misread the build sheet and didn’t solder in those Caps and it made the pedal really frustrating until that negligent error was figured out. Thanks to the DIYStompbox Forum for pointing out my mistake. Use it! Anyways, I now have an awesome boost pedal that I’ll never let go! Well worth the every bit of the frustration. Outside of my mistake, it was an incredibly easy build! I highly recommend this one! Kevin, good Job Sir!

Gott FET PreAmp

Project: Prism (Boss FA-1 FET Amp)

Build description

This was my first attempt at using a transfer for the graphics. I have learned a few things and I am confident that my next attempt will look nicer. I used the HA1457Ws and they sound good to me. The circuit seems to add a nice tonal quality (even when set at unity) that I can’t really describe but is pleasant.

This is my third Aion build and I have really liked the PCBs. All the components have fit very nicely. My other two projects were the Refractor and Stratus, but the enclosures are pretty plain vanilla right now so I haven’t posted yet.

I used the HA1457Ws. I didn’t have any sockets so they got soldered in.

Prism Build

Project: Prism (Boss FA-1 FET Amp)

Build description

This is the second of these I’ve built, great boards as always! This is a nice sounding little box, that can be used as a boost, eq, and all around tone-shaper. It just makes things bigger.

I used the HA1457w’s, not sure how much of a difference if any they make, but I had them, and was happy with them in the last build.

Well worth the time to build, both as an effect but also to just have around as a little “problem solver.”

FET Boost and OCD

Project: Prism (Boss FA-1 FET Amp)

Build description

Built these two to replace the entire bought originals and I have to say absolutely awesome projects/boards! A/B’ing with the originals they are bang on. Love the additional diode options with OCD, I went with green LEDs.

Def some quality boards, straight forward builds, no issues. Love them! Looking for an excuse to do some more……. : )
