I haven't tried it at higher clock rates yet. I probably will, but it's a case of diminishing returns. To go from 4ms to 3ms, I would have to push the clock from 6MHz to 8MHz. It's a big jump.

But it's much easier to control the delay with the M65831. In its "easy" mode (not using an MCU to control it) there are four inputs to select one of 16 different delay ranges, and then you only have to vary the clock over a few megahertz to cover that range. The longest delay with a 2MHZ clock is ~197ms, while the same clock gets you ~12ms in the shortest range. And if you drop to 1 MHz, you can get it to ~400ms. And it still sounds fine, to my ear.

So this one chip can go from metallic flanging and phasing, through various kinds of chorus, plate reverb, early reflection, room / hall / cave echo, spring reverb, all the way to true echo / delay.

The only downside I can see is that it's a 24-pin IC, rather than the 16-pin PT2399, so it's not as compact. But it's available in SOIC packages, too, so that shouldn't be too bad a limitation.

It's originally a Mitsubishi IC, but clones of it are everywhere. Anyone else tried this IC? Thoughts on it?

This will be slightly #geeky, and probably only of interest to #electronics hobbyists and #guitar players. I happen to sit in the intersection of that particular #Venn diagram.

When I was a teenager, having only been playing guitar for a few years, I owned a guitar #effects pedal that went on to become legendary - the Boss HM-2 "Heavy Metal" #pedal. Its sound is still ubiquitous in metal.

I don't have it any more. I think I traded it for an analog chorus, which was a seriously expensive pedal back then. Although I have other #distortion effects, I've missed it a lot over the years.

Well, lots of hobbyists build their own effects. And the circuit schematics for many effects, particularly the classics, are available online. So like many others, I decided to build my own HM-2.

This image is the schematic for the #HM2. It's not the most complicated pedal, but it's a league above something like an Ibanez Tube Screamer. As far as active devices go, it's got 6 #opamps and 10 #transistors of various types, along with a bunch of diodes for multiple types and stages of clipping, and the usual jumble of capacitors and resistors. Oh, and four potentiometers.

Mammoth Bassist had lost Bass man. So Anthony Bass man from Snake was asked to come in since he played fantastic with them. For Anthony it was launching pad into good music, giving great high pitched backing vocals
