I've tried lots of Wampler pedals, just didn't get on with any of them. I've had lots of expensive and 'boutique' pedals, but I'm actually quite impressed with the range of cheap Joyo pedals.
Im generally not that keen on TubeScreamers, they work best with single coils, they can be a touch muddy with Filtertrons Though, the best Tube Screamer clone I've had (i've had lots) is the Joyo Vintage Overdrive. Great pedal.
I really love my Joyo Sweet Baby. It does compress, a bit on the bass, and a touch on the treble, but mids are good. My Fender amp is hyper sensitive to pick attack, and my hot HiLotrons are too. Together, they're a handful, but the Joyo reigns the guitar in just enough, to allow me to produce some astonishing tones. I set it to light breakup. Play lightly, it's clean, whack the strings, nice growl.
I also like the Joyo Ultimate Drive. It's a higher gain pedal (based on the OCD), great for punk and rock. It's a very competent, and good with humbuckers I can't knock it. It can also be used for light gain, but the Sweet Baby is more tweaksble at lower gain settings.
Another good all rounder is the Boss SD-1. I have one with the asymmetric clipping mod (switchable, you can turn the mod on and off). Again, distantly related to the Tube screamer. I think you would like this one, I also believe Mr Setzer likes these too.
In a very different flavour, K.Y.LL Drive by Doombastard FX. It's a clone of a Univox Unidrive, very similar to a Creepy Fingers Doomidrive. It's a fat sounding overdrive, with a good gritty boost. If you crank it, it has monstrous bass. On max drive, it gets quite fuzzy; it's an interesting pedal, very different to anything else I own. You can get a very Jimmy Page type of tone out if it. It's a lot of fun.
Dan, I'm off travelling again soon, so happy to post a few of these off to you to audition for a few weeks. Let me know which ones you want, i will send them on.
All the best
