Considering adding one to the lineup. Doubt it'll be used all that much, so hate to spend a whole lot. I've tried both ends of the spectrum- Empress (awesome) and TR-2 (gets the job done), but I see the Pulsar, Catlinbread, Voodoo Lab and Demeter get good reviews as well here. Also looked at the MXR, Fulltone and Guyatone online. No clue what to get... Thoughts and comparisons? Thanks.
