The following guarantee, updated on 1/10/2023, applies exclusively to custom tone controls purchased directly from Stellartone.  If you purchased your Stellartone product from any other source, please contact the seller for assistance.

30 day Satisfaction Guarantee

Try one or two ToneStyler® custom tone controls in your bass or guitar for 30 days. If you are unsatisfied for any reason, you may return one or both ToneStylers to Stellartone® for prompt refund of the returned merchandise price less the 4% processing fees charged by Reverb.com, PayPal, or VISA/MC.  The shipping costs, and any sales taxes collected via third party marketplaces, are non-refundable.

Stellartone's 30 day satisfaction guarantee is limited to a maximum of two ToneStyler controls per each customer, buyer or user.  After the initial purchase, repeat purchases are ineligible for refund.

Stellartone products subsequently purchased for continuing research, development, and compatibility experiments, are ineligible for refund under this 30 day satisfaction guarantee.  Untested instruments may not produce the same satisfactory performance and ease of installation as experienced in your previous instruments.  Before making any repeat purchase, utilize any ToneStyler on hand to preview the performance, compatibility and satisfaction in new instruments.
