![]() The Super shared the same Output Transformer as the Pro and Bandmaster and would saturate fairly easily. This same idea proceeded further when higher power speakers became available. An easy way to get more clean volume is to remove mids. He knows this circuit very well and may have heard of someone adding a mid as I know he really prefers amps with mid controls. It is possible what is being called a mid pot is actually a raw control. The reason I am even mentioning this is I think you dig the tone you have and I do not think it is a 5F4.Īre all the pots 1 meg? Take a close look at this schematic and consider what would happen if you lifted the ground on the bass pot and added a mid. But this is on a Blackface and some Brownface amps.Ī 5F4 has 2, 1meg Volume Audio pots, one bright and a 1 meg linear on treble and the same on bass. It is common to replace a 6.8K resistor from lug 3 of the Bass pot to ground with a mid control. As a matter of fact, I am sure it is not. I do not think ripping it apart is a bad idea necessarily, but I think what you are hearing is not a Super 5f4. I found if you change anything in this circuit, the change is significant and re-voices the amp. Modding this circuit is not very common and I have spent a lot of time with them. Also, if there is a master volume, how is if implemented. Would you mind marking where a mid control has been placed. I would start by trying to confirm that the amp you are looking at does actually match the schematic for the 5F4 Super.an accurate schematic will help guys help you get it rightĪttached is the 5F4 schematic. That alone will give you the feel of having a completely different amp at the flick of a switch and should clean it up a bit. The Tweed tonestack is mid-heavy and not as lossy as the mid scooped Blackface tonestack. Most involved - try a different tone stack, since you have all of those empty control locations, you could implement a switchable tonestack network. there is a chance that the NFB ratio is incorrect because most "builders" don't take this into account when they use a different secondary impedance than what was originally designed ![]() The builder says "currently wired to 2 ohm". Try increasing NFB (put a 56K resistor in parallel with the existing 56K or use a pot and dial to taste) Replace the first preamp tube with a 12AY7 (less front end gain- as 5F4 was intended) (1) g 34th rectifier tubeallory 150 series tone caps ![]() "Your looking at a 90's fender super amp gutted and converted to hand wired 5f4 Tweed super amp only the two inputs are wired and the first vol bass treble and mids control this is a 35w Tweed circuitĬlassic tone multi tap output tranny 2/4/8 ohm I roll off the volume on the guitar, and by the time it's "clean" it's at a whisper. My question is: Even with single coils, I don't get it to clean up too much (amp volume above 2.5). IT SOUNDS GLORIOUS! It's got that dirty ZZ top, Keith Richards, vintage rock tone. Built a head cab for it and hooked it up to my standard 2x12 cab I use for most stuff. I recently bought someone else's project, a Tweed 5f4 super amp chassis on ebay because he already did most of the work and I got it for less than I could buy the loose parts. ![]()
