Classic Tube Reverb Unit
Reverb Unit Accessories


Based on the famous Fender Reverb Unit of the 60's the Classic Reverb Unit is the benchmark for great reverb tone. Whether you need cavernous space or subtle ambiance this unit will deliver. Mix, Dwell, and Tone controls give the play many tonal options. The foot switch allows for tube buffer bypass so there is no signal loss when the unit is off.  The sound is warm and deep as only a tube drive spring reverb can be. So throw away those lack luster pedals and get real tube reverb.   

Optionally you can add bias wiggle tremolo.  Bias wiggle gives you deep pulsating  trem sound!

The Classic Tube Reverb uses quality parts available and will exceed any reissue in terms of sounds and serviceability.

Customer Comments:

“Hi Carl-Happy to report my Carl’s reverb/tremolo unit arrived safe and sound today. Both effects sound great, and the the build quality is most impressive. FYI,I’m glad I elected to keep the original grill cloth. Again,thanks for being thoughtful and thorough, and checking with me re the detail questions.The gold sparkle cloth goes well with the smooth brown telex,and is right in step with many circa 1964 reverb units I’ve seen. Hope you do well.Your obvious commitment to quality is refreshing these days. All the best!”

“Hey Carl,

Got to play with the Reverb Unit yesterday.  Really digging it! I love how the cosmetics turned out man!  There's definitely a nice depth to the reverb and a good drippy bounce when the dwell is turned up.

I've often heard that outboard tanks have a volume drop, but I don't notice any with yours, actually seems like a slight presence boost when engaged, which is awesome!”

I've had some time to play through the reverb unit you built for me.  It's way better than I remember my old Fender and Gibson stand alone units way back in the mid 1960s.  To say I am pleased would be an understatement.

"Hey Carl.  I picked up the reverb unit Monday.  Arrived in good health, looks great, sounds great.  Build quality is clearly excellent.  Thank you for your good work and prompt service on this order.  I'm still getting to know the unit, discovering settings, and getting a feel for how it reacts to the front end of my amp (currently using it with a Mesa LSC and it sounds a few other Fender-type amps (including a Tungsten Cortez, i.e. 5e3!) I'll be trying it on as well).  Some gorgeous tones...huge range with the reverb, and the tremolo sounds great too.  So pleased to find a unit with post-reverb bias vary tremolo.  And its quiet as a mouse."




Just wanted to thank you for the awesome reverb tank.  It’s giving me that warm tone that I was looking for. Excellent workmanship.  I appreciate the great packaging job also.  Feel like a kid at x-mas time.
