+1 for the MXR M-104. My favourite sound from all the tests on that page. Has a lovely thick chewey sound on the Sawtooth 303MFXxx wrote:Anything making a 303 scream for $29 is a no brainer...
The MXR M-104 or tak your pick http://www.acidvoice.com/tb_303_best_di ... _pedal.htm
how about something more unique

Everything in the circuit contributes to the sound, including the op-amps. For the TS-808 the JRC4558 op-amp isn't pushed into slew rate limiting, but there are many other parts of the op-amp that contribute to the tone and distortion characteristics so I've included them in my model. The slew rate limit for the JRC4558 is 1 volt / micro second, which is included in the model anyway, but I had to lower that value down to around 0.05 volts / micro second before I could hear much of a difference.pilgrim_heart wrote:Since some people swear that changing the OP makes a big difference to the sound I've speculated a bit about whether this might have anything to do with the OP slew rate. It seems to me like if you drive the thing hard enough that you get something approaching a square wave at the op output then the speed of most transitions might be slew-rate limited. Out of sheer curiosity I would like to ask if you've tested anything like this and if so if the slew-rate actually makes any difference? If so I guess that could be candidate for a parameter.
Slew rate affects some designs more than others. The Rat, for example, seems pretty sensitive to opamp used.

Thanks. I've been wondering about this for a while so it was very nice to have this answered, seems like my speculation went in the wrong direction though. That still leaves me a bit curious about this, do you think there is anything to idea about getting huge (the people I've seen claiming this have mostly claimed that it's pretty drastic) changes in sound from switching the OP and is there any OP characteristic that would be the main "culprit" in this? (If you don't want to answer this for business reasons I fully understand.)andy-cytomic wrote:Everything in the circuit contributes to the sound, including the op-amps.

I'd never thought about that regarding the Rat, really interesting. Thanks for the links too, I really enjoyed reading a few of the analyses at electrosmash.resynthesis wrote:Slew rate affects some designs more than others.

I've never been a TS guy, but I've got a mid-90's Rat (with the Motorolla chips that people seem to value so much in these) that I love. A spot-on software version would be nice, as would a nice vintage Big Muff. The DS-1 is ok, but not necessary IMO. They cost what? $40? And they're pretty much ubiquitous.meloco_go wrote:IMO with the gazillion boutique pedals on the market it is better to get a few of the basic ones first -- TS, Rat, Muff, DS-1.
Andy, how's latency on this? Would it be possible to get no latency at 1x oversampling?andy-cytomic wrote:The plugin will also feature input / output level controls, mix, and the regular Cytomic oversampling with realtime (x1 to x16) and render (x1 to x64) options.
I know "Tube Screamers" went through a ton of revisions and different chips with people arguing over which chips/revisions sound better, so if possible, different chips would be nice. Analog Man covers some of the various chips/differences in the various revisions.andy-cytomic wrote:Any other mods?
Setting the DAW to 96kHz = No latency @ 1x/2x oversampling in the Drop/Glue.Funkybot's Evil Twin wrote: Would it be possible to get no latency at 1x oversampling?
Well, yeah. But I think having some basic distortion pedal (not fuzz or overdrive, and not those new complicated ones which try to be something else than a simple stompbox) might be quite useful.Funkybot's Evil Twin wrote:The DS-1 is ok, but not necessary IMO.
