Re: Favorite cheap Tube Screamer based OD
I have an Ibanez TS808 and an MXR Classic Overdrive, and I have A/B'd them both against my friend's Electro Harmonix East River Drive.
The ERD is a bit over 60 bucks, but it's still not an expensive pedal, and it is well-made. It is close to the Ibanez TS808 for sure. It is a little bit less gainy and a tiny bit less middy, but other than that, it's a good cheap alternative to the TS808 that sounds like 95% the same.
The Classic Overdrive was a Guitar Center exclusive version of the GT-OD encased in a cheaper enclosure, but it's supposedly the exact same circuit inside as the GT-OD. It's a mighty fine pedal. It has an internal switch that flips between GT-OD mode and Zakk Wylde overdrive mode. I think these went for like 40 dollars new. You can find them used pretty often.
GT-OD mode has a TS-ish vibe, but the gain knob has more range. At its lower setting, it has a tad less gain than a TS808, and at its highest, it has a ton more gain. The tone knob also behaves a bit more aggresively. A bit more output level too. When they are dialed in to sound as close to each other as they can, the Classic OD and the TS808 do not sound the same, though. The Classic OD has less mids, more bass and treble (but it's still mid-hyped, just not as much as a TS), and the voicing of the overdrive is a bit less compressed and creamy than a TS.
In Zakk Wylde mode, the overdrive is a bit more compressed, brighter, and has even less mids and has less output level. Not scooped-sounding, mind you, just quite a bit less of a mid-hump to it which pushes it more towards Boss SD-1 territory.
The Classic Overdrive is a far more versatile and slightly more natural-sounding pedal while still maintaining kind of a TS-ish vibe. The TS is a classic, though, and if you want that sound, the Classic OD doesn't quite nail it. It can get close, but it doesn't quite have the creamy mids of the 808, and the EHX is closer. I'd recommend both, depending on what you want.
