[linux-audio-user] Re: Spring reverb?

"I am working on a tune that needs surf guitar. The CAPS AMP IV does a great Fender Twin, and the #4 cabinet in CAPS Cabinet II seems to do pretty well as a 2x12 open-back Fender cab. But the classic surf guitar sound of course includes the high-pitched plinking of a Fender Twin reverb spring slapping against its metal case. If you haven't heard it, it's kind of like entering the V'Ger central core, but really high-pitched and fast, and in 16th notes while double-picking. Picking out a muted barre chord into a spring reverb turned up way too high, you can definitely *hear* the springs." Despite the way this should be a very non linear and random kind of reverb, convolution reverbs with a spring reverb sample do this surprisingly well. There are plenty of convolvers around, and loads of samples out there (noisevault is good). I made my own stereo impulses by recording both ends (both in and out as outs, impedances way off, but who cares) of a spring reverb tray and giving it a thwack with a drum stick. I use SIR running on ardour-vst on a computer dedicated to reverbs and other heavy DSP. Connect via netjack, chuck artificial latency on the sends so it comes back in time, and bob's your uncle. (may not be as easy as it sounds, contents may settle in transit). I've tried some other non vst native Linux convolvers, but have not found one as efficient yet. Recommendations welcomed.
