New (long-awaited) RAT clone

It took me a year to build this thing. I bought all the parts back in winter '10, finished the enclosure, then got busy with other things and didn't get back to it until now. I wanted a Rat, but pedalboard space dictated it had to be a Boss-pedal footprint or smaller. It's built on a "Slow Lorus" board from Madbean. This was a low-budget build, so I drilled a surplus 125-B enclosure that I got for free because it had no back plate. The box was prefinished in redish-pink (or maybe pinkish-red) powdercoat, hence the name "Rosie the Rat".

The photo doesn't show the true color - it's more pinkish than orange for better or worse. Meh, it's what I had in the junk box. You can't see it in the picture, but the finish on the top is uh.... textured. Yeah, that's the ticket, it's textured. What that means is, I accidentally bought a can of Krylon GLOSS clear acrylic instead of my tried-and-true satin acrylic. The gloss started to wrinkle the powdercoat, but I noticed in time, let it cure, and resumed with the satin. (Another box I was painting at the time didn't get off so easy; I had to sand it down to the primer and start over.) In the end, Rosie was not built as a work of art - she's meant to be stomped on with a pair of funky old red Converse hightops.

Nothing out of the ordinary inside. It's an old-school LM308 Rat, with an added switch to provide LED (Turbo Rat) clipping in addition to the standard diodes. The center switch position gives no clipping diodes for yet another sound.

With any luck, I'll get a chance to try it through my amp later in the day. I finished it so late last night that I could only test it through my Vox Amp Plug, which doesn't take boost or dirt pedals well. However, early indications are, it sounds like a Rat. I'm glad I changed my mind at the last minute and added the 3-way clipping switch; there seem to be a lot of different tones in there with the "LED" and "none" options.

Cheesy goodness! I had a chance to play it through my 18 Watter clone (with the MiniMASS turned down to bedroom levels). I had forgotten how totally nasty a Rat can be.

The bottom is kind of farty on the low strings below the 7th fret but the upper registers sing. I love how Rats kind of bubble slowly with this ever-changing harmonic structure. It sounds like rolling lava, threatening to explode at any moment. Rosie certainly has as much dirt as I'll ever need, which is exactly what I built it for. My "normal" lead sound is more "ampy" - either a hot clean boost or a clear, dynamic overdrive (Eternity or modded SD-1). Rosies' job is going to be over-the-top fuzzy stuff, and infinite-sustain special effects.

I always had a thing against Turbo Rats - I remember trying one 25 years ago and leaving with a negative impression. Gearmandude's YouTube demo of the BYOC Rat clone reinforced that negtive image; I just liked the diode clipping better. But now, I'm really glad I put the LEDs and mini-switch in Rosie - all three tones are different and usable. The center position probably won't get used much since I have my normal OD/boost pedal instead, but if this was my only dirt pedal then I could see using all three positions a lot.

I can't wait to crank it up, take off the "blanket" and get a listen to more of the high-end detail. The end game is going to be a shootout with my Monte Allums Recto Mod DS-1; another great distortion pedal but maybe a bit too polite for my needs. Rosie should fix that problem easily.

Awesome! I ****ing love Rats.

I really dig that little cheese graphic too. Which control's that for? Filter?
 
Re: New (long-awaited) RAT clone

I love it. Something about that color, those knobs and the overall layout just screams "want".
 
Re: New (long-awaited) RAT clone

Rats have their own sound to be sure. I've got an old (20+) R2DU. It's two rats in a rack space unit with a footswitch that connects via a DIN cable. The power jack is a bit flaky so I've never used it live. You can run the two in series for some out of this world over the top fizzy goodness. The tone does sort of "boil"

Heck, I'm going to plug the vermin in tonight!
 
Re: New (long-awaited) RAT clone

At one point in the distant past, I owned three Rats - an '84 small box and an R2DU. I believe Adrian Belew invented that beasty.
