Light and Loud, Plug & Play Ease of Use
Unsurpassed Tone, Punch, and Clarity
The Choice of the World's BEST Bass Players!
Thunderfunk Bass Amps are the direct descendents of the amp that Jaco Pastorius loved,
the legendary AMP BH-420, improved, and handmade in the U.S.A. by Dave Funk.
With an all-aluminum chassis, the TFB750-A weighs in at only 21 pounds.
Quieter than other amps, with two great sounding DI's, it's perfect for Studio or TV use.
The Thunderfunk's tone is achieved by using high quality film caps in the preamp's signal chain...
just like a high quality mixing board. Twenty-five times more expensive than electrolytics used in other amps,
film cap's tighter tolerances maintain phase coherence through the amp, producing a focused punch unlike any other amp.
Add two to three times the filter caps of other amps, you get a round,
focused bottom that doesn't roll around the stage but instead projects into the room.
Dynamic range is a function of power, transient response, and quiet.
We purposely don't use toroid transformers as we've found they don't sound as good as the old-fashioned "EI" iron.
And to reduce hum, we add a "hum-bucking" wire across the transformer to inject hum into the preamp's ground
cancelling the radiated hum achieving an amp quieter than an equivalent toroid powered amp.
With our unique "SS/Tube Switch" you'll be able to choose from a super clean solid-state
tone for slap and double bass playing, to a gutty, warm, tube-tone for all the rest.

"The Switch"
"The Switch" came about in September, 2003 when I spent some soundcheck time with LeAnn Rimes' bassist, Victor, and brought two Thunderfunk amps with me. We AB'd these two amps along with his EBS system. I had made a change to my design that I wanted to test, and the result was that the amp sounded more like the EBS... more "HiFi" and to my ears more "sterile." I decided I liked my original tone better, but then I thought, "Why not just put in a switch?"
"The Switch changes between the original High Voltage power supply that feeds the power amp, and a separate Low Voltage power supply that gives a more hifi tone. It is subtle. It's not some dramatic tone shaping circuit. It's a change in response and texture. The more sensitive your touch, and the louder you're playing (as the effect is more pronounced when the High Voltage power supply is sagging more). the more you'll hear the difference. It's NOT a two channel amp. It's NOT intended to be changed mid-song as it's not silent. It's just another option to setup the amp for use with different instruments and styles. The Switch is not a tone shifter. In the "tube" position there's more upper mid-range honk." Dave Funk
Some Secrets of Thunderfunk Tone
Customer Comments
Kristjan Aunver
After "searching for the sound" for more than 35-years as a bass player in different bands I think Iīve finally found it.
This is an amp that you can throw any bass at - whether itīs a custom Alembic,
a fretless Rob Allen Mouse-bass or an obscure Lew Chase, the Thunderfunk amp will deliver an optimized sound.
It brings out the true persona of each instrument! You just canīt fool it.
The ease of handling is very much appreciated, too... intiutive is the word.
I use it with Schroeder and Epifani-cabinets.
No mistake there... and band-members that Iīve played with for 35 years have this comment,
"Now ALL of your basses sound good,"
which makes me really happy! I believe that the best amp goes unnoticed - it should just let you express yourself;
how your fingers work the strings is your sound. By the way...dialing in a solid double-bass sound is as easy.
Thanx, Dave! Best regards from Sweden/kristjan aunver

Ok so I've spent a couple days with the Thunderfunk amp. Wow, this thing sounds awesome! I have it running through my Schroeder 4x10 cabinet. All three of my basses - a Passive Fender, an Active Sadowsky Jazz Bass and a Passive Nash P-Bass sound incredible. I don't know how to describe it, I guess I'd call it Thick and Powerful. Sort of an all encompassing sound to it...really BIG. My other amps, an Ampeg SVT Classic and an Aguilar DB750, both very powerful amps, did not deliver this type of tone through the very same rig/basses. Great job man! And for only weighing 16lbs. - It doesn't get any better!! I'm really happy with it.
Todd Cox's Mini-SVT
Hello Dave, just wanted to give you an update on my ongoing experimentations with your handiwork.... Well, I have created the worlds smallest SVT rig. I swapped out the drivers in my Eden 210xlt with Eminence Deltabass drivers, had it rewired, now I have a 700-watt 210xlt @ 4-ohms. Guess whose head went on top? I had three bass players play thru this rig at a small club gig last Friday, and it is God-awful loud for barely being knee-high. I kept up with a half-stack! The headroom and low end are simply too huge. I have found that SVT voice, with a little bit of bite, via the Eden tweeters.... Sweetest sounding bass tone I have ever had. Bless you, man. My back thanks you, as do my ears.... I now look at my WT-400 like an inbred stepchild.
I honestly think it's the best amp you can get at any price.
THE NEW TFB610a
The new Thunderfunk TFB610a speaker was designed to be the perfect match for a Thunderfunk amp. It's a one cabinet solution, perfect for filling the house, while providing you with stage monitor function. You don't have to play as loud, yet you'll still hear yourself. But if you want to tear the place up, this one cab will easily handle 800-watts without any stress, and project deep into the room.
If your transpotation isn't bigh enough for a 6x10, you can still get great Thunderfunk sound with the soon to be available TFB410a. Or, put a TFB410a under the TFB610a and connect them in series with the specially wired 1/4" jack provided on the speaker, or connect in parallel by using the amp's Speakons.
The TFB610a is rated at 800-watts, with 1,500-watts of woofers. The tilted top makes it easier to hear yourself on stage, even in difficult rooms. 6-10", 1-6", 4 soft-dome tweeters, 97dB, 40"H x 24"W x 18"D, ~85 lbs with neos. $1599
The TFB410a is rated at 600-watts, with 1,000-watts of woofers. 4-10", 1-6", 3 soft-dome tweeters, 97dB, 32"H, 24"W, 18"D, ~60 lbs with neos, $999.
