Sonic Research Shrinks the Turbo Tuner

Ask any guitar player, or instrumentalist for that matter, to name an indispensable tool and a “tuner” is probably at the top of the list.  That is unless they are one of the fortunate few with perfect pitch.

Announcing the ST-300


Sonic Research is known for making accurate strobe tuners.  Their ST-200 Turbo Tuner appears on many pedal boards.  Joining the current trend of manufacturers making smaller or mini-sized versions of popular pedals (e.g. the Mini-TS9 or the Nano POG), Sonic Research has developed the “Turbo Tuner ST-300 mini“.

Similarities or Differences

At first glance, almost all features of the ST-300 are comparable to the ST-200.  Both tuners are accurate to +/-.02 cents.  I did notice that the ST-300 does not support battery operation.

Accuracy Comparison

To get an ideal of just how accurate the ST-300 tuner is, here is a comparison to a couple of other popular tuners.  A more accurate tuner (+/- 0.2 cent) is necessary for proper intonation of a guitar.

Boss TU2 & TU3: +/- 1.0 cent
TC Electronic Polytune 2: +/- 0.1 cent
Sonic Reseach ST-200 & ST-300: +/- 0.02 cents


The ST-300 is expected to begin shipping in mid-July 2015.  The price is $129.99.  I definitely see a Turbo Tuner ST-300 on my pedal board in the very near future.
