Fixed Resistor network in place of HRM ?

[pedro]

All,

I'm quite keen on the "set it and forget it" approach and was thinking about trying a fixed resistor network in place of my HRM board. I want to stay "HRM" for now.

I find myself messing too often with the HRM settings, but have never really landed finally on the sweet spot settings

I'd quite like to try a fixed resistor network instead and would like to get opinions on values to try where some of you have measured the HRM values in original dumbles or in your own building experience.

Of course I realise that the HRM board enables me to tweak to taste with different guitars, but I'd like some ideas as baseline to work from to try this idea out. I'm mainly a Humbucker player - PRS McCarty and Ibanez AM-100 - if that helps.

Call me mad if you want - but tell me what you think on starting values !

Has anyone else tried this approach ?
cheers
Pete

forgot to say

my circuit values are all as per ODS-101 at moment

pedro,

My experience was the same until I finally landed on the settings that worked for me on most/all of my guitars. IMHO it is a necessary evil to have variable control there for the very reason you mention - to flavor it to your taste or guitar of choice. Perhaps a solution would be to make a "dummy" board with trimmers - find the settings most desirable in your amp - then yank the trimmers and measure them to replace with closest resistor values. It took me an eternity to land on a "sweet spot" in my HRM. I'm very happy now and glad the controls are/were there. Kind of a love/hate thing. My desire was to closely match the tonality of the OD section to the clean tone so that I did not have a major timbre change between my clean and OD on switching. I eventually got to some settings that allow me to use the OD without the PAB. FWIW I ended up with my bass trimmer set fairly high - 2 o'clock or a hair more - the treble and middle were 11 o'clock or less. Oddly enough, close to where my front panel tones are most of the time: 11, 11, 1 o'clock. Perhaps more can chime in on their trimmer positions. The best of luck in finding your "D-spot"
