I have one.
I like it. I use it in my office a lot.
I got the version 2 at the upgrade/intro price as well. I have yet to dive into the newer features, but the sound is great.
Some things to note with the original Spark 40.
It IS a practice amp.
You could gig it, but expect to mic it. Expect it to not be a great monitor for loud stages.
There are mods for sending output to something else.
You can do headphones out to a powered speaker. Needs a specific cable to either sum the two channels or split the two channels and go into a stereo powered speaker.
Don’t do any of that. It works but it’s the one thing everyone birches about and asks for help with in the groups.
It’s not difficult. It’s just a workaround to get something out of the amp that it wasn’t intended to do.
You can’t really loop with it.
You can put a looper in front, but if you wanted to record a loop, change tones and then play over the recorded loop, it’s not going to work.
Because the looper is on front and it’s going to feed your dry signal into the tone engine to whatever setting is current.
Sure, you can set the amp to a clean tone, front it with a bunch of pedals into a looper and go that route, but then you’re effectively bypassing the entire reason for the amp - the modelling.
There’s more that people have griped about, but mostly because they wanted it to do more than was ever intended.
Positive Grid HAS release new gear that addresses all of the gripes.
The Edge is a cool busker-in-a-box machine, for example. It was released last week. So, not quite shipping yet.
There is a powered cab that works well with the Spark40 that makes it giggable as a head-cab kind of setup.
There is the Spark Live which is more of a gig-ready solution.
Anyway, back to the Spark40.
If you dial in 4 tones that you like, you can save them to the amp and never touch the app again.
You can even get a foot switch to switch the presets.
It’s a bit boomy. Get it off the floor and it gets a lot better. Utilize the EQ, or put one in front and you can make it better.
Also, about the built-in EQ: it eats up the modulation slot in the chain. So, EQ or chorus/phase. You must choose.
There are slots for delay and reverb though. So, you’re good there.
Also, you can’t change the order of the effects in the chain. (I hacked it to work, but haven’t used it at all since.)
Also, you can’t stack similar effects. So, one drive/fuzz/distortion; one modulation, etc…
Despite all the gripes, I still like it and use it at least once a week.
I plan to setup the Spark 40 and the Spark 2 on an amp selector and also goof around with wet/dry or stereo type setups.
Upgrades require a PC or Mac.
The newer models can be upgraded over WiFi with the app, but the 40 needs USB and a personal computer. (Last time I checked..)
Some people managed to brick their amps while upgrading. I’ve never had any real issues.
If you download from the cloud, each tone will have its own volume setting.
Expect to have to adjust it to your liking and then save the new settings.
A lot of people griped about that “Why is the volume different for each preset?” Blah blah blah….
It’s a blast running through all of the tones that people upload to the cloud.
