Peavey Fury Content, I like his video's

A USA Peavey newbie apparently!...The issue with some techs is they tend to be in a hurry....you cannot hurry with Peavey TR's, be observant first....i use a quality thin wall socket and will remove just a 'tiny bit of wood' with a hollow Rotobroach if necessary to get full, even access to the nut and use a vacuum to clean it out or compressed air.....sometimes there is just a tiny bit of splintered wood in the way ime as on my 85 Foundation.

Wiggle the socket or wrench just enough to get the socket set 'fully and evenly' on the nut.....like i mentioned, a bit of splintered wood was keeping the socket from full grasp on the nut.....otoh, my 89 Fury was clean access to the TR and was missing the TR cover so someone had done the tightening properly

My 85 Foundation was bowed pretty severely......i wound up removing 2 of the tuners to gain access to the TR......it took many slight adjustments to get it right and you could see the nut had been 'boogered' just a bit by a previous person who did not have the wrench fully on the nut.

All was fine in the end but i was sweating the 85 Foundation initially LOL!

which way do I move the toggles to make the treble response more "responsive" I want to be able to roll it all the way off

?

I get it, but I don't get it. clockwise makes for more treble

counterclockwise =less.

But I just want more control of it, not necessarily less?

does that make sense?
 
@kkaarrll

The trim pot inside basically adjusts how loud the bass is when swapping from active to passive.
That's what the miniswitch does,it's active/passive.

There's no real fine tuning going on with the Dyna preamp.
I found it is best to set this for unity, no difference in volume between passive and active. My Dyna5 is an oddity because it was an early prototype there is no passive tone control. There is something special about those SF pickups.

Would you post a picture? On the SF Dynabass, the High control and the passive High rolloff are a dual pot on the same knob. Which one works is controlled by the Active/Passive switch.
 
it's a cool bass man
I love my Dyna, too. My black/black chrome is the "Hell" to the white/gold "heaven". haha.

I did the same on my Dyna, as well as with any active/passive bass I have. Set the volume/gain to unity so both modes are the same volume. Keeps it simple and more versatile on the fly.
My first time playing my Dyna was quite an eye opener. Such great tone, I was blown away by what that 33 year old preamp sounded like. Of course, SFs are the best sounding pickup out there... :D

I do wish it was a concentric knob. I tend to run my treble at the middle, flat indent. Switching to passive mode puts the tone at 5, which is about 5 numbers too low for my passive tone tastes. I'm sure an afternoon of tinkering can result in a usable mod to make it so.

The bass is brighter in active mode, regardless of knob setting. I'm sure some of it is the lower impedance and less loading, so the signal is not mellowed out via cable capacitance. I also wonder if there isn't a little treble boost baked in. It was pretty common to do that in the 70s and 80s with active preamps. Early Stingrays, my G&L El Toro and other basses of the era usually had pretty bright preamps and some had treble boost mode in the preamps, too. I did a small resistor mod to make the active mode more smooth like the passive mode in my G&L. Perhaps there is a similar mod that can be done to the Dyna pre to do the same?

It has the dual pot and Dyna circuit so looks the same, the fault is in the initial wiring that I never had repaired. At the time (and still) I prefer that bass in passive mode wide open making any tone adjustments externally.
