What I Repair
Hands-on bench work for tube amps, synthesizers, and music electronics. If it has circuits and it's broken, I can probably fix it.
Tube Amplifiers
Retube, bias, recap, hum diagnosis, intermittent faults, and full restoration. Fender, Marshall, Vox, Mesa, boutique — all makes and eras.
Synthesizers
Vintage and modern synth repair. Key contacts, voice cards, power supplies, calibration, and component-level troubleshooting.
Guitar & Bass Electronics
Pickup swaps, rewires, jack replacement, shielding, pot cleaning, and full setups with intonation.
Pedals & Effects
Troubleshooting, switch and jack repair, component replacement, and modifications. All brands and formats.
Pro Audio & Backline
As a working backline tech, I service professional audio gear across all major brands and touring systems.
Custom & Unusual Jobs
Circuit design, one-off builds, vintage restoration, and weird projects that other shops won't touch. If it's interesting, I'm in.
Why Rudi Makes
What You Get
Real Diagnostics
Every repair starts with proper diagnosis — not parts-swapping. I trace the actual fault before I touch anything.
Direct Communication
You talk to the person doing the work. No front desk, no middleman. I explain what I find and what it costs before I proceed.
Documented Work
Every repair is logged — diagnosis, fix, parts used. You get a clear record of what was done and why.
Fair, Honest Pricing
$45 bench fee applied to your repair total. Labor billed at published rates. No surprises, no upselling.
Warranty
30-day labor warranty on all repairs. If something I fixed comes back, I make it right.
Working Tech, Not a Reseller
I'm a bench technician and backline tech — not a shop that farms out work. Your gear stays on my bench from start to finish.
How It Works
The Repair Process
From first contact to finished repair — here's what to expect.
Reach Out
Email me with what you've got and what's wrong. Include the make, model, and symptoms. I'll let you know if I can help and give you a rough idea of timeline.
Drop Off
Bring your gear to my shop in Indianapolis (by appointment) or to Jonas Productions. I'll do an intake and confirm the reported issue.
Diagnosis
I put it on the bench, trace the fault, and figure out what's actually going on. Then I contact you with findings, options, and a cost estimate before any repair work begins.
Repair & Test
Once approved, I do the repair, test thoroughly, and document everything. Standard turnaround is 3–7 days. Rush service available.
Pickup
I let you know when it's ready. You get your gear back with a written summary of the work and a 30-day labor warranty.

FAQ
Common Questions
How much does a repair cost?
All repairs start with a $45 bench/diagnostic fee, which gets applied to your total if you proceed. Labor is billed at published hourly rates (typically $55–65/hr depending on the work), plus parts at cost + 25%. I always confirm the estimate before starting. See full pricing.
How long does a repair take?
Most repairs are completed in 3–7 business days. Complex jobs or parts-dependent repairs may take longer — I'll give you a timeline estimate at diagnosis. Rush service (48-hour turnaround) is available for an additional $35.
What brands do you work on?
All of them. Fender, Marshall, Vox, Mesa/Boogie, Orange, Peavey, Ampeg — and boutique or vintage amps of any make. For synths: Moog, Roland, Korg, Sequential, Yamaha, Oberheim, and more. If it has circuits, bring it in.
Do you work on solid-state amps?
Yes. While tube amps are my specialty, I troubleshoot and repair solid-state amplifiers too. Same diagnostic approach, same documentation.
Can I ship my gear to you?
I primarily do local drop-off in Indianapolis. For special cases (rare gear, out-of-state clients), reach out by email and we can discuss shipping arrangements.
What if my gear isn't worth repairing?
I'll tell you. If the cost of repair exceeds the value of the gear, I'll let you know upfront so you can make an informed decision. You only pay the bench fee for the diagnosis.
About
Who I Am
I'm a repair technician, backline tech, and builder based in Indianapolis. I fix amps, synths, and electronics — and I build custom projects from circuit design through final assembly. I'm comfortable taking something broken or half-formed and turning it into something that works well and lasts.
