So, tar baby, do you use the OD with both knobs turned off as a push-button mute?

No--I have a volume pedal--use it for volume swells as well.So, tar baby, do you use the OD with both knobs turned off as a push-button mute?

I use my Rumble 100 on gigs, and I never use OD or contour . I used to use vintage all the time, but lately I’ve been digging the Rumble “au natural”The contour & OD buttons don't work for most of what I do.

(And one of the nice things about controls--you can have them on or off & you can turn dials up or down to suit what you want)
For me the nicest one & the one I use the most is the Vintage button---it's almost always on for me.

Cool, I haven't tried the Rumble 25, just the 40 & 100--I got my 40 through a Reward program-and it does what I need it to, I wouldn't mind one of the higher wattage models though--some have feature the 40 doesn't.I use my Rumble 100 on gigs, and I never use OD or contour .

with the 25, it’s “bedroom tone” all day, so I’m enjoying the thing for exactly what it is- an at-home practice amp!
side note, the OD button on the 25 (just a button, no level/drive control) kinda reminds me of the vintage button- not exactly the same tone, but adds volume, thickness and compression like vintage does![]()
I was a little hesitant to try the 25, as it doesn’t have the controls I’m used to. But I was pleasantly surprised with what I can get out of it.Cool, I haven't tried the Rumble 25, just the 40 & 100--I got my 40 through a Reward program-and it does what I need it to, I wouldn't mind one of the higher wattage models though--some have feature the 40 doesn't.
My previous practice amp for bass was a Trainer TBM 10--which was greta value for the money--and works for playing at home & with small groups without drums,.I was a little hesitant to try the 25, as it doesn’t have the controls I’m used to.

I also wouldn’t mind having a 500c in my arsenal as well![]()
I could actually try that... didn't think about it... Thanks!
I got a free frequency generator app recently called Hz and ran it into the line in on my Rumble 25 and 100.
You can set the frequncy generator for a slow sweep or operate manually,
Set it at a mid range frequency like 500 or 1000 and have the volume at a good level and then move the frequency around to hear where it is dropping off. Off course your hearing is a factor, but you can run it into a good stereo or bigger system for comparison and check your hearing.
Sounds like a great weekend!Well decided to use a feature of my R40 that I thought I would never really use. Normally, I practice with my bass plugged directly into a mixer with rehearsal recordings inputted via a computer and a mic for vocals. My partner decided to go away for the weekend (outrageously great weather in up-state New York USA this weekend in what has been a quite cool and rainy Spring) so I could make some "noise".
I took out my R40 to the patio, and plugged my MP3 player in the Aux port, Jazz bass in the Input, and had a band rehearsal using some rehearsal recordings. I am quite surprised how well the R40 sounded as a portable mono system. I have my EQ close to functionally flat (B: 9:30, ML: 2:00, MH: 1:00, T: 9:30) so this most likely helped but it did surprise me how well this worked out considering a single 10" speaker and no high-frequency driver.
I know others have commented how well this works out and I want to add my name to the chorus. The R40 works really well in this situation.

I am in Saratoga Springs, NY. About 10 years ago I had a chance at a lecturer position at Ithaca College which I wish I had pursued more aggressively. The only time I have been there was driving from Rochester to Baltimore in March 1975 but I have read it is a very nice progressive little city. My partner has a house in Hamilton, NY where I am at often.Sounds like a great weekend!
PS where in NY are you?? I’m in Ithaca!![]()
It’s open.Did they relax the restrictions down there in SoCal, or are you guys rogues?
With both the 100 and the 200, I, too, used to always use vintage, but now only if I need extra 'oomph' for a specific room. And it's been so long since I/we played out, I don't remember which rooms. Starting settings are still 10, 2, 2, 10-IIRC. (damn CRS)I use my Rumble 100 on gigs, and I never use OD or contour .

BTW how is/was/maybe will be the music scene there? Saratoga Springs was fantastic for a city its size. I feel Saratoga Springs will come back to some degree but it will be awhile before it is anything close to what it was.
