Univox EM-350

This box is smaller than I expected. About half the size and a quarter the weight of a Roland Space Echo. Pretty nice if you have to lug it around. 4 knobs-Volume/rate/balance/repeat. Pull the repeat knob and you can listen to everything you played for the last 2 minutes. I bet the tape can be spliced with standard hi-fi cassette tape. It looks to be the same thickness. Im not sure that my repeat knob works. I hear 1 loud repeat followed by (maybe) 3 more quickly decaying taps. Turning the repeat knob makes little or no difference to the volume of the taps.

Compared to a Roland Space Echo, this unit is quiet. The balance knob is effective for mixing direct signal in with virtually no signal loss. Echo (and noise) can be mixed in as desired. However, this box does not have near the POWER of a Space Echo. I think this only has one playback head and one record head. It doesnt really feedback upon itself like I wish it would, but it does its thing, and it does it well. The rate knob adjusts the servo motor tape speed. It gets mostly short delays but not super short. A bit longer than an analog delay pedal and not as short, probably 70-400ms give or take 50ms. This box really shines on vocals. Just think of John Lennon's slapback voice on "imagine" or "instant karma". A nice ultra warm, compressed tape overlay. I notice that the tape "warbles" often while playing back , but it sounds great when this happens. Sometimes it sounds like a temporary flange or chorus effect. That is the beauty of tape echo! I found that you can double the delay time by running the wet signal of a stereo delay stompbox into it (i used an ibanez ADL). This gives you a delay of a delay. This will degrade yr high-end response x2 but is worth it for super-spacey sounds.

I can't comment on this. First off, it's tape delay and can sound messed up even when it's working fine. Also, I have only had the box a few days.

I think Univox was bought out by Korg and completely dismantled.

I think this is a keeper. Im not sure how much use this thing will see on guitar (since I already have delay pedals galore), but it's just so cool to have around for those certain sounds. Studio work would be ideal with the playback feature. I think Eddy Van Halen used a similar univox model to record solos, then play them back and use the speed to do dive bombs. It is also fun to record a solo on a slow speed, then crank it up to the next octave and hear a maniac-fast solo play back. Check out Cream's "deserted citied of the heart" for a similar sound. some parting rants:TO HELL WITH DIGITAL. DIGTAL MUST DIE. DIGTAL DIDJA NO GOOD. MP3's ARE FOR WHORES (who are these stupid people that pay for MP3's?!?) STAND UP FOR YR GOD-GIVEN RIGHT TO REAL ANALOG MUSIC!
