Re: Slap back echo pedal?
For slapback, I like the crappier pedals best. I want the repeated sound to be almost nothing like the original sound tonally. I want it to be like a multifaceted concrete wall giving my sound back to me, but like I'm outside in an alley or a schoolyard so there's no second repeat, and no room ambiance along with it. I had an Arion Stereo Analog Delay back in the day, and it was perfect for that. They reissued it, and I'm happy with the Tubulator, so by proxy I'd say I could recommend it, but I haven't seen or heard these reissues so I don't know. But for less than $30 my bet is that it will melt your face off.
Again, we're totally talking personal preference. Some guys like the slap back tone to be an exact replica, like the Boss DDx pedals, so take my opinion with a grain of salt. A slapback tone that's an exact replica of the original sound is more reminiscent of old studio tricks, like doubling the track and physically delaying the second track, either because of staggered tape heads, or a delayed bounce. But creative miking of real slap back is more approximated with cheap analog delays IMO.
To me, the sound comes at you so fast that you don't need to analyze the complex tonal signature with a slapback echo the same way you would with a longer delay. It's more like you have to decide if you want it clean or dirty, expensive or cheapo. Slapback, unlike reverb or chorus for example, is an area where you can underspend and overperform IMO.
