I think I’m very close to pulling the trigger on the Vox Cambridge50. The question I have I've asked in a thread I started about the amp, but I want to "cast a wider net," as it were, to get other impressions as to whether or not I'm understanding how this modeling amp thing works in principle. Those who are not owners of the Cambridge50 but have the VX50 GTV, or the Valvetronix amps might be able to contribute to this. And some may be able to speak to whether modeling amps other than Vox products work on the same principle. I just need to be sure I understand how to use the tech before I pull the trigger. I’ve never even seen, much less test driven, the Cambridge50. So for my decision-making process, it’s very important for me to confirm that I truly do understand how the amp works, and how it could work for me. Basically, the amp in its manual mode is when top panel settings—amp model selection, EQ, effects—are engaged. Manipulating the control knobs on the top panel directly impact the amp’s sound. But when I press (or click with the VFS2, which I already have) the PROGRAM mode, I get a factory preset available typical of each amp model selection. And that also in PROGRAM mode, I can create/write my own user program, save it, and then in performance with a click of the footswitch I can recall that user program for my instrumental break, then with another click of the same switch, I’d be back in manual mode. So, for example, I’m playing on the “Boutique CL” for my clean tone during the verses of a song, with just a touch of tremolo and spring reverb. Then, for an instrumental break, I click the footswitch and bring up my user program A, and presto! My tone is now the “Brit 1959” amp model, with phase and echo for effects. Then, when my lead part (or what passes for lead playing when I do it ) is done, another click of the same switch, and I’m back to Boutique CL with trem and verb. Have I got that right? This may seem like a very basic question to many, but the truth is, I’ve never owned a modeling amp, and I’ve never created or recalled a user program. Even with my BOSS ME-70 multi effects pedal, I’ve never done presets and programs, never written or created them. I’ve only ever used it in manual mode. So I’m asking: do I have the right understanding of how this works? The only member here I know of that has this amp is @scattitude but I’m assuming that the principles are the same with most modeling amps, and that owners of Katanas or Nextones can speak to this in principle as well. Thanks in advance, y'all. If you want the benefit of reading the manual on this amp before venturing an answer, I understand. Here is the link to that pdf document...https://48r18hv56p93dbg741fo98ui-wp...uploads/2020/01/VOX_Cambridge50_OM_EFGSJ1.pdf To make it simpler, I've taken screenshots from that owner's manual and pasted them here. The first screenshot is of a portion of page 4 of the Vox Cambridge50 Owner's Manual. The rest of the images are from page 7.
