Quick Hit: Yonac ToneStack Review

A super-flexible virtual guitar rig for iOS.

The idea of an entirely virtual rig isn’t as foreign to the current generation of up-and-coming guitarists as it was even five or 10 years ago. ToneStack, the latest iOS app from Yonac, is an all-in-one suite that speaks to a wide range of digitally adventurous tone tweakers. For the cost of a pack of strings, you get a good selection of amps, cabs, mics, and effects, as well as an amazing amount of flexibility in designing your signal chain. If your palate goes beyond the included assortment of toys, ToneStack offers additional amps and effects as in-app purchases.

Once you pull up a preset, you can drag and drop each element of your signal chain to your heart’s content—even A/B cabs, amps, or entire effects chains. At times, the virtual knobs can be a little difficult to dial in accurately, but for the most part, the app feels snappy and responsive. I plugged in with a Mexican-made Stratocaster and was able to dial up reasonable takes on Gilmour’s saturated “Pompeii” lead tone and R.E.M.-esque warbly tremolo. A 2-track recorder is also included, which makes bouncing and sharing riffs and demos a snap.

Test Gear: Fender MIM Stratocaster, Apogee JAM


Affordable. Includes 20 effects. Inter-App Audio and MIDI functionality.

Difficult to dial in specific settings on the more complex effects. Some of the distortion pedals sound thin.

Students at the O’Brien Guitars school bind their instruments following a more traditional European style of guitar making.

Finding the right school can be tough for any aspiring luthier. Here are some options to consider.

In my previous column, “So, You Want to Be a Luthier?”, I talked about the types of people attracted to lutherie training programs, some of the possibilities and options these individuals have at their disposal, and discussed both long-term and short-term training, either of which have their place for primary or supplemental training. But the question remains, what school should you choose for your lutherie training? And what might a school have to offer that would best suit your educational needs?
