First Pedal Build! (Large Images)

WashburnBasser · #1 03-02-2009, 08:03 PM

Since our schools were closed due to the snow today, I decided to go ahead and attempt my first basic pedal build! I decided I wanted a true bypass loop with a feedback switch, since I've been wanting to activate my filter and phaser simultaneous lately.
Observe the results of my several hours of work! (Sorry for the large crappy cell phone pics)

Gutshot!

As you can see, fitting everything in the case was a chore due to the 16 gauge wire I had and the crappy drilling job on my part. I also didn't do the greatest job soldering. However, everything works and it sounds awesome. Here is a clip of me playing with it, making some cool noises and fiddling some knobs... I have a distortion in the loop.

Clip!

Did you follow Beavis Audio's design: http://www.beavisaudio.com/techpages...cker/index.htm ?

If not, there is same thing you did but with an added feedback pot for mixing.

I actually used his true bypass schematic and then just connected the input and output together to make it loop, with a switch in between.

I'm confused. What exactly does the pedal do? Also, what'd you build the box out of?

Haha, I didn't build the box, it's a standard MXR sized Hammond enclosure. The pedal is a standard True Bypass Looper, except I added a switch that causes everything in the loop to feedback. In that clip I had a distortion pedal in the loop.

Ah, okay. Sound clip is great. You can definitely get some cools sounds with the feedback switch. That gives me ideas for future designs.

Nice! That's fun! I like it!

Yeah, it's a fun pedal. You really do need to have a distortion or some pedal with a buffer in there to control volume spikes though. Using is with just a phaser made an extremely loud burst of sound that scared the **** out of me! I'm also kinda tempted to try and sell these, although I would definitely plan them out a bit better and actually use the correct wire and solder. I bet I could sell these pretty cheap, with a bunch of different options....

That's what the feedback pot is for - controlling the volume of the feedback with respect to the send signal. A buffer won't do you any good with volume spikes but a compressor would. Or you could add a low pass filter to cut frequencies above a certain point.

Yeah, unfortunately the jacks I used and my poor prior planning means I can't add a feedback knob.
