Exactly as expected

It was this or an MXR. I've owned MXRs in the past and wanted to try something different. The Bad Stone is a winner. Vintage sound with modern switching and, I hope, reliability. For the price, I don't see how you can go wrong.

Electro-Harmonix Bad Stone Phase Shifter

Don't get me wrong I love the MXR Phase 90, who doesn't? But this pedal is much better...........I use it in the manual position with the shift at about 1 o'clock, it's usually on all the time. This is a great pedal and in the auto mode it has the MXR again with FeedBack knob. Price is great. If want a phase pedal, this is the one to get.

Love it

Does eveything you ssid it would!

Small Stone With Extra Versatility

I was recently quite content to get another Small Stone to replace my long-gone original, but the Bad Stone came back on the scene and I ended up buying it instead. I won't overrated it, but it does just what the phase shifter should do, and some more. I would say the overall sound is similar - essential 70-s-style phase shifting, with the added versatility of manually adjustable depth and better feedback control - to the Small Stone. The manual mode reminds me of the Electric Mistress filter matrix mode and can be dialed in to expand your lead tones, but I intend to buy a Mistress anyway as it has a much more pronounced 'stop' sound in the filter cycle effect if that's what you're looking for. The Bad Stone would be better with a blend knob so it doesn't overpower the signal; it makes a bit of line noise as well. If your phase shifter needs are simple for guitar or bass, I'd stick with the Small Stone, but the Bad Stone does provide another level of control to work with. Either one provides great, funky phasing.

Great sound, bad switch

My review of this is simple: it sounds wonderful - exactly as it should in a very simple nostalgic way. The price is excellent as well. Unfortunately, the switch makes a loud pop and that is the only reason for my 2.5 stars. I bought one and returned it because of the popping switch. The replacement I received seemed better - until I got it on stage and the problem returned. I'm just going to keep it and live with it. Love the sound, hate the switch. Also notable, Sweetwater was above and beyond in terms of their return policy and customer service. 5 stars for that!

Sweetwater Advice

Electro-Harmonix Bad Stone

The feedback control is useful for moving from vintage flavors to more experimental phase tones that leverage the Bad Stone's metallic resonance, while manual shift mode transforms the Bad Stone into a unique filter. It's a powerful and intriguing sonic tool at a great price....
