psarkissian,
Thank you for the warning. I would very much like to purchase an original Native Instruments power unit for my amazing Variax 700!
I somehow lost or misplaced my cabled power kit. I searched everywhere for a new, or even a used one and it is nowhere to be found. The guitar is really heavy because of the batteries and I am not getting any younger. Having to pause in the middle of rehearsal (or song) in order to replace the batteries is also annoying.
I had a beloved FirehawkFX that died on me a year ago. The local NI representative at the repair shop told me that as it is out of warranty, and there are no spare parts (chips) available in order to fix it, that basically it is not fixable. I would actually purchase a new one but they are discontinued.
So I am stuck. I believe and hope that this static, simple, yet effective handmade device can solve my problem (coupled with a proper 9V AC AC 2000mA regulated power supply), fingers crossed.
Purchasing a Helix in order to power my Variax is not a feasible or desired option.
So please advise, highly appreciated.
