The Tremolo: Reviews
Overall: An excellent instrument.
Price: Between $10 and $20 plus shipping. So far I have experience with these purchased from Tmart; when I bought my two, they were $15 each from this source, now down to $10. I just discovered a possibly new (at least, probably English-language new) web site of the Swan company itself, with an excellent selection of tremolos.
Keys: All major and minor.
Size: 24-tone is available in all keys. 16-tone, 21-tone, and 28-tone are available in C.
Box: Nice plastic box.
Physicality: Good strong plastic comb, behaves as if it will last quite a while. Good sheet metal covers.
Tone & Tuning: Excellent for the mids and highs, OK for lows as long as you're not looking for the mellow wood sound. Solo-tuned for full octave runs on that long 24-tone range. The tremolo tuning is excellent, neither too loose nor too tight. Very satisfactory timbre. Not un-Suzuki-like, but a bit more emphasis on the highs and a bit less on the midrange. Chords and single notes play well.
Downsides: None so far.
