Rockerverb Style Tube amp


Recommended Posts

Hello!

Recently, in my mind came the idea ..

Overdrive Rockerverb style channel- Rockerverb topology with some tone shaping modifications

Clean/crunch channel - I designed it a long time ago ..

Tubes: 4 x ecc83, 2 x 6v6

Front Panel :

Overdrive: Pre Gain, Post Gain, Sweep, Bass, Mid, Treble, Volume, Clean: Gain, Tone, Master Volume

and few switches to the channel configuration.

Today I made a preamp section :)

Yes this is my own design. I started to design and make guitars and guitar tube amps 9 years ago. Overdrive channel is a channel similar to the orange Rockerverb drive channel, but it has been modified to have more control of gain / drive response. Clean channel has been designed for guitarist Emil Gruca, and it is in his signature tube combo, I slightly modified the tonestack in this project.

Here are a few samples of clean channel :)

Thanks!

I made the front panel here like this: first, aluminum chassis was sand by water sandpaper, later brushed by several different metal brushes, I printed by laser printer labels on the foil and transfer the labels by heat gun and I painted transparent varnish. This method is very good because I can transfer whatever I want, and in any colors :)

I'll have to try that, thank you for the tip :) I have done the same thing but I used an iron to make the transfer. That also works but it's hard to get a really nice transfer that way (probably not hot enough).

I always use this foil http://www.folex.com/htm/580/en/X-10-0.htm?Article=47670

Viderekommen I tried a lot of methods to make the transfer. Iron is good to transfer the pcb. When you work with chassis you losse a lot of heat, Iron is too weak.

Today I installed a power transformer and speaker transformer, I finished wire clean channel and the inverter. I'm still waiting for one octal tube sockets :angry:

"I guess you will post a drive channel video soon?"

When amps will be ready I promise !

But recently I recorded with my friend a few samples of this preamp. Samples are recorded on a 1xEl84 Class A 5W amp. Gain was in the middle. Clean sound is turn down the volume on the guitar.

No effects only guitar -> cable -> Amps

I'll post if I find a sample with a higher gain

Some news :)

I finished the power Stage, added a choke in the power supply section. Power stage has switches between Class A / Class B and modification of the dynamic response and frequency of power stage.

I made a speaker cabinet and amp cabinet. Cabinets are made from plywood with a finger joints, I used Hide Glue.

    • Jeg har de akustiske alltid i kasse med en Boveda pose i kassen. Funker fjell.
    • En tur alene til byen, kom hjem med åtte nye skiver (Ecclesia, #3 i midten fikk jeg forrige lørdag):  
    • Jeg oppbevarer mine heltregitarer (archtop og kasse) nesten uten unntak i gitarkassene. Rommet jeg oppbevarer gitarene i har «bedre» (for gitarer om ikke annet) luft enn resten av huset, men jeg har et hygrometer for å følge med på fuktighet og temperatur. Så langt har det stort sett vært innafor i rommet (35-60% fuktighet). I enkelte perioder om vinteren har jeg satt inn en bolle med vann for å tilføre fuktighet. Det funker, men jeg skal vurdere å anskaffe en liten luftfukter.
    • Brum brum. Neida, skaff deg et hygrometer (hundrelapp eller to), så følger du med utover vinteren. Ingen grunn til å fukte lufta så lenge du har inneklima innafor "normalen". Men absolutt lurt å ha forholdsregler: Jeg har en heltre granlokk Ayers stålstrenger som ikke greide seg gjennom den tørreste og kaldeste vinteren i trøndelag på lenge (10-12 år siden?) uten betydelige sprekker i lokket. Den hang på veggen i stua, og jeg hadde ikke begrep om luftfuktighet da. Den låter og spiller nydelig, så det er foreløpig kun kosmetisk, men så kosta den bare omkring 5000,-, så ikke noe stort tap. Ellers, hvorere du borhena? Innland/kyst/fjell? Har litt å si.
    • Takker!  Hvor mye legger dere i luftfuktighet og slikt for kassegitarer? Fikk med en pakke d'addario humipak, men tenkte det er lurest å vente til vinteren med å poppe den? Gitaren kommer til å ligge i kassen når den ikke er i bruk. Er første heltre kassegitar jeg eier, so bear with me
