EC-80/EC-100 Echo Chamber
- Replacement Tapes that need to be modified to work used to be available from
Dictaphone. The model number is
0645180 (180 Sec.) and is labled "Announce Cartridge", they are $9.50 plus postage.
The erase head on the tape will not make it in the
slot of the Dictaphone tape cartridge ( Too Narrow) and one must remove
about 1/8" piece of plastic from the side to allow the erase head to come
close to the tape.
If you call dictaphone at 1-877-805-5903 ask for Valerie Carlson, she is aware
of what we are using the tapes for.
- The EC-80A has a very short delay time by comparison to its other tape delay rivals. If you replace the "Echo Delay" potentiometer from the stock 5k Ohm to an 500k Ohm you can get a much longer delay out of the unit and still have the short slap delay like the 5k Ohm provides. - Thanks Brian Healy
- The tremolo arm and spring for Hi-Fliers can be replaced rather cheaply with Fender Jaguar parts ordered from
- If you don't like the three on a strip open gear plastic tuners of the
sixties High-Flyer (Mosrite copy) and you don't wnat to alter your
guitar in a way that can't be reversed, there is a solution. W.D Music
Products makes a three on a strip chrome tuner with metal oval knobs
that are shaped like the High-Flyer knobs. The closures over the gear
resemble Mosrite Kluson tuners closures. And the best part is that they
fit the guitar exactly. Even the mounting screws fit in the old holes.
They are vastly better tuners and the old ones can always be put back on
without leaving any taletale mystery holes. Thanks to Hobbes
- I've seen complaints about the sound of the pickups on Univox Moserite basses (farty
is how I heard it described once). Well, I replaced the bridge pickup in my Univox w/ an
EMG Bass Humbucker nad I can say that the sound is many times improved, I might even replace
the other pickup soon.
- Bill Machrone has a page on installing a new bridge in a Univox bass at
Also, here's some info he sent on installing fret dots in the neck of a Univox bass:
"I've also included a photo of the side marker dots we added. Using a
hobby saw, I cut thin slices off an aluminum nail, drilled holes the
same diameter, and glued them in place. I smoothed them with fine
sandpaper taped to small sticks of wood, then covered them with clear
nail polish. Anyone trying this should be careful to cover the side of
the fretboard with tape and drill through the tape in order to prevent
splintering the finish or the rosewood. You need a drill press, a very
sharp drill, and a jig to hold the neck vertical on the drill press
table." - Bill Machrone
- The Neptunes have had a double neck Hi-Flier made for them out of a white Hi-Flier bass and guitar.
- If you are rewiring a Hi-flier bass, apparently a Fender Jazz Bass schematic acan be used to figure out how to connect everything.
Univox 335 Copies (Effie, Coily, Custom)
- Someone has informed me that the current Yamaha 335
copies are almost exactly like the Univox ones, they appear to be built exactly
the same. This means all the parts (including pickups) should be interchangable.
- RadioShack has knobs that might fit well on some Univox amps.
