Amp just arrived, plugged it in, and everything works.

Only tried upright for 30 seconds at a low volume, and spent about 60 seconds playing my Godin hollowbody w/a P-90 through it, so I'll come back later once I've had the chance to actually try it out some more.

That being said, I have one question, and it's not really a Mesa Rosette question - but it is one that I have because of the amp: when my fingers rub the pick guard on my Godin hollowbody, I get a little static through the amp. Doesn't happen when I don't touch the pick guard. Doesn't happen when I touch it and keep still. Only happens if I touch the pick guard and then move my fingers.

I'm wondering if this is just something that's only getting picked up because of the onboard effects or what. Seems like it's a grounding issue with regards to the guitar, not the amp.

So it’s an acoustic guitar amp that also works for upright bass.
:cool:

No. It’s not an acoustic guitar amp. It’s an acoustic amp.

Per Mesa’s website:

Our commitment to producing innovative, reliable and inspiring musical instrument amplification for nearly 50 years finally includes the incredible world of acoustic instruments! The Rosette® Combo combines thoughtful design with the highest quality components, materials and construction to deliver a new standard of detail and clarity in acoustic amplification. Handbuilt in Petaluma, California, the Rosette combo is a compact and powerful 30 lb., 300 watt amplifier that offers ample headroom and accuracy while being dedicated to delivering your acoustic instrument’s true tone. The Rosette Series is designed not just for acoustic guitars, but also for vocals, ukulele, mandolin, dobro, violin/fiddle, cello, upright bass, and and other uniquely acoustic instruments.


Given that the designer of the amp also designed the Mesa Subway series of bass amps, I’m pretty sure he knows what he’s doing. Also should be added that it’s a class D amp with a 10” 8ohm 150 watt speaker, and a switchable tweeter. Speaker appears to be made by Eminence which is a reputable company as well. Finally, it has a high pass filter. It also has a mic input with phantom power.

No reason why it wouldn’t work for bass. I mean, they represent that it does, Eminence makes speakers that are utilized for bass cabinets, and it includes features that are normally aimed at the bass market (a tweeter that can be switched off and a high pass filter).

So anyways, had a few minutes to play around with it.

The “out of the box” suggested settings work good for an Archtop. Probably some experimentation is in order, but it’s a rich full sound.

For upright, I started with everything at noon, and am using an Upton Rev Solo pickup.

Gain I left at noon. Set the HPF at 9:00, but I’ll probably dial that up a bit to reduce how much my house shakes, as my floor is really lively.

Bass took up to 1:30 or so. Low mid gain set to 10:30 and low mid freq at 2:30. Same knob settings for the high mids. Took treble back to 10:00, but it should be noted that I didn’t turn off the tweeter. If I set the tweeter to cut or turn off, I can probably bring the treble back up closer to noon, if not a slight boost.

The question is: what are the corner frequencies for bass and treble and what is the range of the frequency settings.
Does that fit higher instruments better than DB or does it work well for DB if the EQ Settings are not neutral?

So the bass control is 100hz, low mid is 150hz-1.8khz, high mid is 300hz-5khz, and treble is 8khz.

HPF is 40hz-200hz and is 12dB/octave.

Frequency response is 40hz-20khz(-3dB).


There are two versions of the amp, one is the 1x10 (which I bought) and the other is a 2x8. The 1x10 is somewhat mid-scooped (while the 2x8 is not) which makes it warmer than the 2x8 and supposedly a bit easier to dial in. I was on the fence about which one to get, but given that I’m using a pickup in my DB, and I want to be able to quickly dial things in, I decided to go the easier route.

One nice extra is that it does have a tilt back feature — you basically screw/unscrew a small post on the bottom of the amp until its height results in the desired tilt back angle.

I owned and used the 2x8 Rosette for a while in a string band type group. There were two issues that made me eventually sell the amp and move on to other options. 1) I found that I liked the sound of the amp at low volumes but that as volume rose it became harsh, and I hard a hard time dialing that out. 2) I don't know about the 1x10 but I found the 2x8 to be very directional, I had to point it right at me to be able to hear it, and when I did that my band mates couldn't hear it very well.

I liked it for other instruments (guitar, mandolin) but it ended up not working for me for double bass.

Yes, I had heard that sort of commentary on the 2x8. As I understand it, the 1x10 was intended to be the more user-friendly version for basically everyone that wasn’t doing fingerstyle. Now, I haven’t gotten it to rock band levels yet, but hopefully will have some opportunity to try it out with drums in the coming weeks.

Which reminds me, I really need to test it with my nylon string guitar.
