Peavey Decade Stomp

I wonder if Sweetwater monitors this forum? I got two Bit-o-honey's and two Smarties with my Pickup Booster order.

JHS also does a Decade pedal

This isn't a JHS, it's a Ten Years Is A Decade pedal. Looks like they're not making them anymore?


I guess this is the same situation as Boss releasing the HM-2w and knocking most of the Heavy Metal clones off the market.

It is amazing how much the original company doesn't see or understand the market. Other companies take their ideas, and manufacture them, and bring them to market. Only then does the original company realize they can make money on their old designs.

I am not a Peavey historian, but I remember playing and falling in love with a Peavey VTX MX head around '85. It was built in a road case. It was pretty much a Decade-style solid-state preamp with a 100-tube power section. I remember just being blown away by that amp and it having massive gain on tap.

I wonder if my Peavey MP-4 uses this same tone stack? It's a 50-watt SS amp, but the preamp is usable separately.

I guess I am waiting a bit longer. We are working on the song I would like to use the Decade. It has a bridge that is 70s glam rock ala New York Dolls, Sweet, or KISS and I hope the Decade pedal will be the perfect vibe. Another month will not be too bad.

Hi Bruce. Ryan from Sweetwater here. I'm reaching out with an update for the Peavey Decade pedal you have on pre-order with us. Peavey has given us an ETA of mid-April to expect those in. Are you ok with waiting a bit longer? let me know how I can help. Thanks!
 
I got the alert from Peavey this morning, the Decade pedals hit US shores and are in the country. I hope MF delivers mine by next week.

I got it! It is definitely a keeper, but I will say this pedal is not for everyone. It has a lo-fi vibe. If you are looking for buttery, creamy overdrive, this is not your pedal. It is very raspy, almost more fuzz-like than distortion. In its standard mode, it sounds as advertised, like a cranked small solid-state practice amp. 70's style drive with lots of grit and nice touch sensitivity. Maybe too much, there is a bit of string noise when sliding your fingers. When hitting the "SATURATION" switch, it is a gain boost that kicks the pedal into the realm of metal. Those '90s solid-state metal tones are within reach.

The form factor is smaller than I expected, which is nice. Here it is next to a standard BOSS pedal. It is a plastic enclosure, which is fine by me. I will say this pedal adds an overdrive/distortion flavor I previously did not have, so I am very happy with it. The final test will be when I plug it into the 100w amp for rehearsal, and also see how it responds to gain staging.

What does the saturation switch do? Is it clean until you hit that switch?

The PRE handles the dirt so in theory, you could run it clean and then hit the saturation switch for more gain. However, it is not really designed to be used clean, once you get the PRE to around 2, it starts clipping. With the SATURATION turned off and the PRE cranked I would call it early 70s hard rock distortion. SATURATION is adding another gain stage from what I can tell, and gets you a more modern tone, yet still dated. In short, it is like having two dirt stomps in one unit.
 
how much volume boost is there when you hit the saturation button?

Noticable but not a huge jump. A manageable little bump, pretty much what you would want for the lead to jump out. Nothing big enough to give an issue managing your live volume. There is also silent switching, so there is no "pop" when engaging the pedal.

I was working on a song for the band. I decided to plug it into the DAW audio interface. It is dead silent and sounds fantastic direct. No hum, no noise, nothing! Not, the application I bought this for, but I will take it. An unexpected bonus.

The circuit is pretty conventional. This schematic is from a clone kit. It uses a JRC4558 dual op-amp. The first stage has a symmetrical soft clipping circuit using 1N4148 silicon diodes with 100pF smoothing capacitors like a tube screamer. The saturation switch engages a 22uF bypass capacitor to ground which boosts the entire frequency range. Engaging a bypass cap makes it sound louder and higher gain. A Fender Deluxe uses a 25uF bypass cap on the first triode of V2. I don't go above 10uF because the bass response gets mushy. When people mod Deluxe, Princeton, or Champs they reduce the bypass capacitor value to tighten it up and reduce blocking distortion.

After the first stage there's another symmetrical hard clipping stage using 1N4148 diodes. Then there's the tone stack and the second stage is basically a make up gain stage with some smoothing capacitors in a feedback loop but no soft clipping diodes. There's another 22uF non-switchable bypass cap on stage two. After stage two there's another symmetrical hard clipping stage. I wouldn't have expected that after a make up gain stage but its there.

gotcha, thanks for the details. i have plenty of fender amps, so know the 25uf is the standard bypass cap with a 1500k resistor. also... apparently, my eyes are starting to go, had to blow that up a bit to see details :D
