Guitar News / Re: Fender Tonemaster uses digital emulation - but for only one amp model
« Last post by g1 on February 18, 2020, 02:16:00 PM »
I'm working on a new pedal for that.  It's called the Degrader.  :cheesy:

Hey Joe,
I hazzard a guess that Digi models just have way too much bandwidth,, = Fizz at high gain.
Well that is what my ears tell me every time I have to repair one of those all in one COSM roland pedal gizmos. yuk
I have a crappy digiteck modeling pedal thing here that I got for nothing and it's the same issue.

Years back I went nuts trying to resolve the 20/20 bandwidth on an old Quadraverb. For their day they were top shelf gear.
while trying to record some guitar tracks with it I ended up just inserting a simple ANALOG Marshall cab sim between the quad and deck,,,, huge improvement.
From what I can gather not much has changed.
So as you can probably guess I'm not a fan of modeling setups.
A young lad asked me only last week why can't I get the sound of the great players from years ago?
Answer, TOO MUCH friggin bandwidth in modern amps and gear lad.  8|
Phil.

That doesn't seem insurmountable though as an engineering feat.  Here's hoping that they figure that out.

Quote: "Do you think I can just leave the 3rd wire disconnected?".

Again. The third wire is used by the laptop computer itself.

If you simply want to use the supply as an external supply then the third wire is not used.

Schematics and Layouts / IN SEARCH OF : GBX Bass Driver Schematic
« Last post by Lazlos on February 18, 2020, 10:21:33 AM »
back in 2014 jpdesroc posted this topic https://www.ssguitar.com/index.php?topic=3624.0 with hard to find gbx schematics.

sadly the site ( http://www.arcenson.com/public/GBX_amps_schematics/ ) is down and the wayback machine did not archive any of the schematics, it seems like some people on the forum succeeded in downloading.

I am looking for the Bass Driver and Bass Power Amp schematics does anyone have??

thanks!

Amplifier Discussion / Re: Randall rg-80 rg-100 power amp transistors
« Last post by duckduckgoose on February 18, 2020, 08:01:40 AM »
ah I see thank you for sharing

well I found what I was curious about. found a schematic from the 2012 rg 80 and its different. seems they changed up the power output because of those expensive old school transistors. I think there also could be more labor involved mounting the older ones. I assume this is the same thing for their other amps power section just more power.

edit: oh the person that posted it on the other forum was also named g1. lol small world

If it sounds great and is cheaper, lighter and more reliable than a valve amp then why not.

Exactly!  My one beef with any modeling amps I've tried - they don't take pedals well.  And when I say that, it's really that they don't take boosters/light ODs well when you are using them to push the amp to break up like you might on a tube amp.  They get fizzy/ugly.  If they can fix this issue, I think valves can take a back seat for good!

Will just try it anyway. If it works and theres no smoke or sparks then its OK.

That's pretty much it.  For what it's worth, I believe the Dell branded ones are quiet.  I'm sure others are as well though.

regards to sims,, FANTASTIC learning/ teaching tool for noobs like me who wish to understand what the hell goes on inside amplifiers. :dbtu: :dbtu: :dbtu:
And you can't  blow them up if wired wrong or burn yourself with hot irons  :lmao:
Your preamp circuit looks like this with Circuitmaker,, it's not top shelf sim but it's all you need to come to grips with basic amp circuits. (even does Valve circuits if you want)
Cheers Phil.
