Fender Bassman AB165 Mod – Bass Ch. Tone Mod EASY

Leave a comment

This blog post will show you how EASY it is to end up with a Fender Bassman Bass Channel that is ‘guitar-usable’.  This is done without even TOUCHING the tone stack.  If you want an even MORE Marshall type tone, you can either make a few changes to the first gain stage’s cathode circuits and/or make some changes to the tone stack.  (One such tone stack mod that I recommend might be to simply change the value of the slope resistor, so that the midrange isn’t so attenuated.  I will go over this tone stack EASY mod at a later date.

DO NOT MODIFY A RARE LEO FENDER AA864 CIRCUIT!!  ALSO, DO NOT ATTEMPT TO WORK ON THESE AMPS UNLESS YOU KNOW WHAT YOU ARE DOING, AS THEY CONTAIN VOLTAGES THAT ARE LETHAL AND WILL KILL YOU!!!

This is the fourth in a series going over exactly how easy it is to modify a  Fender Bassman. This EASY Bass channel mod is at the request of Jim G., my good friend.  As always, you can click the schematics or pics in order to view them, or download them.  If you need the hi-res schematics, simply ask and I shall email them.  😉  As you can see, I removed the .01 cap in parallel with the 100K resistor.  That cap basically gets rid of all the high frequencies, which you need if you plan to play guitar through the bass channel.  (Remember to leave the deep switch OFF.  If you want to use that channel for bass guitar again, simply turn the deep switch ON.)  Bassman Bass Ch Easy ModAt the right, you see Jim’s amp that I have marked up to show the mod.  (If you are paying attention, you may wonder what the cap that I have circled on the left does….  You can remove that 500pF cap in parallel with the 100K resistor in the guitar channel to ‘open up the high end’.  You might just want to do that as well.

Below are two sound clips of before and after this bass channel mod.  I was plugged into the 2 input on the bass channel, with the volume set to 3, and the treble and bass controls to 5.  I was hooked into a 2X15 Sonic half stack using a 2005 Gibson SG with the selector set to rhythm, and the volume dialed way down to about 3 or 4.  I recorded this using my cell phone, and set the app’s gain down about 16dB since this Bassman is extremely loud even with the volume set to 3.  😀

Fender Bassman AB165 Mod – Midrange Pot Mod

Leave a comment

This post is the third in a series of Fender Bassman modifications.  This one is going to go over how easy it is to add a midrange control.  Here, youmid-potentiometer2 see one place that would be suitable for a midrange control, once you bypass that two prong outlet that pretty much goes unused.  Or, you could easily use the spot where the ground switch is, since you’ve clipped out the ‘death cap’.  Or, you could use the ‘ext’ speaker jack.  Those are the three easiest spots to put it in, with the minimum in work.  Whichever of these places you choose, you will probably need some cloth covered wire to make the changes.  This place, Angela, has everything you might need, from cloth covered wire, to caps, or whatever.

DO NOT MODIFY A RARE LEO FENDER AA864 CIRCUIT!!  ALSO, DO NOT ATTEMPT TO WORK ON THESE AMPS UNLESS YOU KNOW WHAT YOU ARE DOING, AS THEY CONTAIN VOLTAGES THAT ARE LETHAL AND WILL KILL YOU!!!

That being said, here’s a great video showing you how absolutely easy it is to discharge the filter caps in a tube amp.  This is how I’ve done it my whole life.  Remember, when in doubt, measure the B+ with a DMM!

Moving on to this week’s mod….. This is the schematic of the changes necessary. Normal Ch Mid Adj Mod SchematicRevA If you click on it, you see that you only need to change one component, and add the potentiometer.  I have changed the ‘fixed’ midrange 6.8K resistor to 3K and added the 10K pot in series to ground, giving you a nice, adjustable midrange control.  Here, you see the Normal Ch Mid Adj Mod LayoutRevAAB165 layout showing those changes.  There are a few different variations of this as well.  If you would rather, you could just put a 25K pot in place of that 6.8K resistor.  If you want to see how this mod sounds before making it permanent, OR, with the ability to roll it back to original, just lift the end of the 6.8K resistor attached to the potentiometer pin, leaving the other end soldered to ground.  Then, wire the pot to that point.  The 3K resistor changes things ever so slightly, but you will get the idea.

This modification, as well as the one in the next installment help to overcome the ‘scooped’ midrange that these amps have.  If you would rather not have a midrange control, but would rather have the midrange ‘ironed’ out a bit, then the next installment’s even easier mod is for you.

Fender Bassman AB165 Mod – NFB Mod

Leave a comment

This is the second installment in the series of modifying a Fender Bassman amp with an AB165 circuit back to the more desireable AA864 (Leo Fender circuit).

69 SF Bassman
69 SF Bassman

These mods can also be applied to a huge amount of silverface ‘transitional’ amps.  The AB165 circuit was utilized in these amps until 1970.  For the most part, this mod and the bias adjust mod are the bulk of what’s necessary to ‘blackface’ an AB165 circuit.

DO NOT MODIFY A RARE LEO FENDER AA864 CIRCUIT!!  ALSO, DO NOT ATTEMPT TO WORK ON THESE AMPS UNLESS YOU KNOW WHAT YOU ARE DOING, AS THEY CONTAIN VOLTAGES THAT ARE LETHAL AND WILL KILL YOU!!!

This mod will focus on the absolutely horrible negative feedback loop that CBS added.  We will be removing it for the most part, restoring it back to AA864 specs.  We will also be discussing how we can tweek the frequency of the sound as well.

Let’s start off byBassman Innards Chassis NFB Mod taking a look at Jim’s 1966 AB165 Bassman for the areas we will be concerned with.  Marked in red are the main areas of the NFB loop.  Marked in yellow are the coupling caps from the phase inverter stage to the power tubes.  Marked in green is the part of the feedback that we will leave, but possibly tweek a little bit.  Why remove the power tubes’ NFB, you ask?  Because the end result of the NFB are a ‘neutered’ sound as well as lower volume and a ‘sweet spot’ of tube breakup at a higher volume setting.  So, by removing it, you will get: more volume at a given setting and the tubes will break up at a lower volume setting.  (You will get a little more white noise, but this should be able to be minimized by ‘adjusting’ the area in green a little bit.)

Here, we seeNFB Mod Schematic.2016.03.21RevA2 a copy of the AB165 schematic that I marked up with the changes.  (Don’t forget that you can click on it to see it full size.)  First thing is to remove the two 220K feedback resistors as well as to swap the two wires going to the speaker outputs and the feedback loop that is going to remain.  The two coupling caps from the phase inverter stage to the power tubes will be changed from .022 back to the AA864 values (.1).  Also, change the .1 coupling cap (from the output of the gain stage to the input of the PI) to the value used in the AA864 circuit, 500pf.  Also, in order to put the feedback loops back to Leo Fender specs, you need to replace the 47K resistor with an 820 Ohm one as well as remove the .1 cap (with the square around it).  You also need to move the feedback loop solder point to the 22K resistor.  This point is currently at ground, so you need to insert a 100 Ohm resistor to ground. NFB Mod Layout.20160321RevA2

Here is the layout diagram for the NFB mod.  The cap (with the square around it) can be either taken out (to restore the loop to Leo Fender specs), or left in, or changed to a different value (to change the frequency response of the feedback).  For example, going to a .01 cap only allows the higher frequencies to pass (and cancel), getting rid of the harshness.  You can also change the 820 Ohm resistor to 1.5 K Ohm, reducing the amount of feedback felt, and allowing for a better tube breakup.

If you think this through carefully, you can make the cap ‘switchable’ using the ground switch, if you have bypassed it and removed the ‘death cap’.  Or, you could utilize the 1/4″ Ext Speaker jack (if you disconnect it), and make the cap and/or resistor switchable via a latching foot switch.

That conclude this segment.  This mod might not be for you if you want a calmer, mellower  Bassman.  This mod might be for you if you want an aggressive  Bassman with more bite and more volume and better break up at lower volumes, and the ability to ‘cut through’ the music.  😉

Next segment will look at tone shaping.

Tech, music, and general ramblings…..
