Thanks for the head's up.

Did you score one off Ryan then CJ?culturejam wrote:I'm going to guess that it uses a SMD version of one of the Belton chips. It's also possible (although I think less likely) that it's a Spin Semi FV-1.
I'll have one in my hands next week, so we'll know for sure. But I can almost guarantee it's not something you can replicate with a DIY project. I'm not even interested in that anyway...I just want one because they sound awesome.
But still, knowing the ICs might help someone design their own reverb that is beyond what the typical Belton circuit can do.
Yes, yes I did. Thanks so much for the tip!Scruffie wrote:Did you score one off Ryan then CJ?![]()
Ah, okay. Good info.Scruffie wrote:And it's the Wavefront Semi Chip if I recall, mine's not to hand at the moment, it's not the Belton though.
Yeah but what Wavesemi chip is it there are a few different ones, I can see it's a 16 pin soic but which one ?culturejam wrote:Yes, yes I did. Thanks so much for the tip!Scruffie wrote:Did you score one off Ryan then CJ?![]()

You'll have to wait until next week when I get mine. Unless Scruffie wants to crack his open and tell you now.Ice-9 wrote:Yeah but what Wavesemi chip is it there are a few different ones, I can see it's a 16 pin soic but which one ?
I would, but when I said mine's not to hand... it's about 4 hours away in a giant container with all the rest of my stuffculturejam wrote:You'll have to wait until next week when I get mine.

It's probably the AL3102. But I just read that Wavefront is in the process of voluntarily scaling back their entire company in preparation for shutting down.
Yeah thers only two options i'm aware of, i'm sure it's one of theseculturejam wrote:You'll have to wait until next week when I get mine.

I was looking for that thread earlier! I knew we'd discussed it before.culturejam wrote:Here's some info straight from the builder's keyboard:

I couldn't agree more. At first I just didn't "get" what he was doing, but now it's like "what the fuck was I thinking not loving these pedals?!?!?"stanimal08 wrote:If you are reading this and are not familiar with Dr. Scientist pedals, I suggest you check out his forum over at ilovefuzz...
That would be cool, but it's still going to be quite a chore to DIY the Radical Red Reverberator. I think the Wavefront stuff is only SMD, so at least that part of it is going to be tricky (but not impossible of course). To me, it's not worth the effort. I'd rather buy it and enjoy it than slave over it.stanimal08 wrote:And I'll also post gut shots of my big box RRR so you can have a look at the design, the big box is not smd if I recall correctly...

Well for me it's not about building a clone of this, it's more about seeing how other builders go about what they do and why. It's about learning how things tick. I know i could just download the application sheet for that chip and design around that it's not difficult.stanimal08 wrote:culturejam wrote: I'd rather buy it and enjoy it than slave over it.![]()

Most definitely agree.... i want to post pics strictly as pedal porn.... when i first opened up my RRR i spent a good portion of my time staring at the pcb......
Totally. That's what this place is mainly about, even though some people come here just so they can build a clone of something. Really, the point is to learn and share.Ice-9 wrote:Well for me it's not about building a clone of this, it's more about seeing how other builders go about what they do and why.

I would think switching the xtal over while in effect will cause quite a clatter in the sound. I can't think of a better way to do it though. If the wavefront chip has a mute pin it could be done usine that (maybe)Ice-9 wrote:I have noticed from the pcb picture that Dr. Scientist has used 2 different crystals on the toggle switch to change the sample rate of the digital chip allowing the reverb to have a longer delay (lower fi) 12mhz is the standard xtal and the other is 6mhz .
It does indeed Make a Clatter of reverb, you can read it on his site on the Page for the Reverberator.Ice-9 wrote:I would think switching the xtal over while in effect will cause quite a clatter in the sound.
