Usually some attenuation is made of the final output before patching into mixers or amps. The details can be seen on our Technical Information Page. We ask that you do this within 10 days of receipt of the products. If you've damaged or modified a product we can't take it back. See our Policy statement here.
Customer pays for shipping charges.
If a product breaks within the first year after you purchased it, just contact us via email for a return authorization number and shipping instructions. Naturally, if the product was damaged from abuse or modification this warranty doesn't apply. In that case, contact us for a repair quote. See our Policy statement here. No, we sell direct to everyone anywhere.
