Like Dave I have a TC Electronics XL One..great unit. I also aquired a Lexicon MX200, also a very nice unit at about half the cost. Since you're looking for reverb you wont need everything the XL One has. But for guitar you may want to hunt around for an older spring reverb unit, Furman and several other companies made rack mount units. They produce that nice Fender boing kinda sound..that might sound good with a Tubier(TM) sound.
And a power conditioner/regulator of some type is a must.
