FDP Forum / Fender Amps: 1985 - Current / Jazz Settings on Your Blues Jr.

Just wondering how you BJ jazzers set your tone and volume controls on your amp and then also where you're setting your tone knobs on your guitars.

I'm typically putting my BJ at master/9-10, gain/3-4, treble/4ish, bass/7, mid/3.

Guitar (Ibanez AK85 using neck pup only) tone is set at about 3-4 and volume at 8-9.

My tone still isn't quite what I want. I have a Cannabis rex speaker, Ruby reverb, EH 12 ay7 in V1, JJ's. BillM mods are next...tone stack, etc.

With an old Ibanez 335 style i set it

Treble + Bass around 7 or so.
Mids about 5
Vol + Master at 6.
I then listen and adjust for what I hear in the room

I probably like my jazz tone a bit brighter than a lot of the arch top/flat wound players.

Your settings are in the right ballpark. The tone stack and power supply stiffening mods will give you rounder, warmer tone and the presence control lets you take the edge off your pick attack,for a mellow jazz tone.

Bill:

Would those mods be enough to achieve the jazz tone or would you recommend any others?

You'd probably want to do the TwinStack mod for more tone flexibility--you can pull out all the mids for a scooped tone when you want it, or more of a Wes or Larry Carlton tone by dialing up more bass and using the mids to push the bass strings into mild distortion.

I try to get jazz clean tone with no midrage on at all. Maybe back of on your guitar volume a bit. You need the billm mods to get the best out of the amp. I also have a cannabis rex and ruby tank. Some of the tones we seek acually come from 6l6 tubes or larger amp if you will. A delay unit used modestly can give you some tones that you might be seeking. It kind of makes the overall sound a little richer. Make sure the amp base is up to a least 7. Run your treble as you like, mine runs from 6 to 8. Most of the jazz guys use .011 and up strings. If you are comfortable bending .011's then that will also help the tone. I try do play a bit like Larry Carlton so I have to use .010's as he does to get those great bends. Larry is not your usuall jazz player. He adds blues and rock to his jazz which is why I admire him.

Really...no mids? I'll try it. My Ibanez is a ES-175 knockoff,hollowbody. The tone I'm more looking for is like Pat Metheny's. I use .012s flatwound strings. I'm getting there; Bill's mods are definitely the next step. I may also add a 250K pot for a mellower tone, instead of the 500k pot I have now.
I use only the neck pup, which is a Dimarzio Virtual PAF. I think it's a pretty good pickup so far.
I guess the quest for the ideal tone never ends, does it?

I would suggest a good graphic eq pedal - you can do lots with that!

I have only used the midrange once on my BJ. For some reason, semi hollows with humbuckers just do take take to the midrange IMO. Knock off guitars like mine, are really much brighter than the guitar they are trying to copy. The tonewood is not as great. The midrange seems to amplify this shortcoming. Thats interesting about the eq pedal what does it do guru?

Jazz,

What EQ do you recommend? I have a DOD that sounds a litle metallic and doesn't work for a mellow jazz tone.

Dave, did you turn down the midrage? did you like the sound? Tom

I can get a great jazz tone with my Epi 335 and Blues Jr. My amp has a Veteran 30 speaker (Warehouse guitar speaker's version of the Vintage 30). I've got a Tung Sol 12AX7 in V1, so nothing unique there. The V30 speaker really adds great midrange. I run the preamp vol around 4, master around 5 or 6. The bass at 7 or 8, mids around 6 or 7, treble around 7. Roll off the tone on the guitar and volume. I use .011s on the 335. When I had an Ibanez AF75 with flatwounds this amp and settings were instant Wes Montgomery (although my playing isn't). The speaker really adds the smooth mid-range and rolls off the annoying blues jr. treble. hth

Tom,

I turned down the midrange all the way and I didn't care for the tone. It sounded better with a little midrange; like 3-4. It helped when I turned the amp volume up a bit and rolled off the guitar volume some. That made for a less trebley tone and warmed the sound a little.
Apparently my tech installed a linear taper pot instead of an audio taper pot when I had him upgrade them a while ago. The guitar volume doesn't come on until about halfway. I'll have to switch it to an audio taper pot.

I've been following this thread with much interest. On thing I've noticed is no one has mentioned if they have the "Fat Switch" engaged.

I generally don't use the Fat switch. It's a little too heavy/muddy for the tone I like.

It's more useful for distortion/drive tones.

My Epi Sheraton 335 just does not like the midrange. It's a very bright guitar to begin with. I agree with Bill, don't use the fat switch to much. Without the midrange on my guitar sounds much bassier. I also put in a 12ay7 to help things a bit.

Reviving this thread, I am a beginner, have an Epiphone Joe Pass Emperor II, stock setup and a Blues Jr. w/Jensen speaker. Trying to get a smooth, mellow jazz sound, would very much appreciate suggestions on settings for both amp and guitar. Thanks in advance!

I moonlight in a jazz quartet and use my heavily modded Blues Jr. Along with the BillM and other mods... I put a 12ay7 in the v1 preamp and a 12at7 in V3. It really warms and tweeds the amp up. I also put in a Eminence CRex speaker in...being hemp its quite warm yet kinda border line dark though. However, I really love Jensens RI's (IMO a super fine speaker line for Fender type amps) so I wouldn't change the speaker. What do you have? A C12N? I use that in a vintage Twin and just love them once they became broken in. For Jazz.. I run both the master volume and volume at half way. push the mids and base... totally get's the job done (big time)
