-Since TVP-1s are only available used now, prices on TVP-1s tend to vary from around $135 up to $180 or so. They aren't wildly priced "booteek vintage" pedals because it seems they never were high on anyone's attention list. That said, if you're interested in getting one, be on the lookout, some TVP-1s are very beat-up. Others are almost pristine and prices on auction sides and forums doesn't seem to correspond to the particular conditions of the pedal.

-The easiest way to think of this pedal is that the left side of the pedal controls the the Tremolo effect, and the right side controls the Volume effect. What doesn't make a whole lot of sense is that when the left side of the pedal, the Tremolo half, is engaged, the right-side light is turned on, and when the right side, or Volume Swell effect is engaged, the left light is on! We'll have to change this so that it's consistent across the usage of the pedal.

 The fact that we're unfamiliar with any music performed with this pedal in any kind of heavy music suggests two things:
-# There's a challenging learning curve on using the variable tremolo speed in this pedal in a musically sophisticated and tasteful manner. The further implication is that this pedal opens up some uncharted musical territory.
+# There's a challenging learning curve on using the variable tremolo speed in this pedal in a musically sophisticated and tasteful manner. The further implication is that this pedal opens up some previously uncharted musical territory.
 # It's likely, that like the Rotovibe, not only can a little go a long way, but by extension, it's easy to overdo this pedal.

 [[Dunlop/MXR|Dunlop]] TVP-1 Tremolo/Volume pedal. This is a pedal that has fallen off the radar of most pedal enthusiasts and at first glance, it's not hard to understand why...
-This is a difficult pedal to master. Just as the wah-wah, so too do the [[JD4S_Rotovibe|Rotovibe]], and the [[CSP001_Variphase|Variphase]] and other treadled pedals require their own learning curve. The Rotovibe is probably the closest, function-wise, to the TVP-1 in that as the treadle is rolled from heel to toe, the modulation effect becomes faster and faster...

 This is in stark contrast to the [[Wah-wah]] where the sweeping of the treadle sweeps the effect. Like the Rotovibe, when the TVP-1 is in tremolo mode, a little can go a long way.
