You can’t directly save modifications to the on-board default Presets (left-most knob on Spark 40). You can save your changes within the Spark App to a new Preset Name, and then assign the new Preset to one of the four Preset LED Channels. To use the headphone jack as a Line Out, you need a TRS-stra...

I found this article on the Spark Amp Lovers Knowledge Base useful. I don’t record from my Spark 40; however there have been a number of similar questions on this topic on the Positive Grid Spark Forum that are addressed in this article. Hope it helps… https://sparkamplovers.com/kb/connecting-your-s...

This should be a relatively simple Preset to create, especially since the video includes most of the amp and pedal information. Start with any existing Preset in the app, “Save As New” to create your starting point, and change the amp and pedal models to match (or approximate) those shown in the vid...

Could be you have really hot humbuckers(?) I’ve noticed that when I download a very loud Preset from ToneCloud, I not only have to adjust the Amp gain and volume, but also the Reverb Pedal settings. The Preset pedal seems to contribute more gain to the output than a real Reverb Pedal, at least to my...

Thanks for the info. I downloaded the Preset from ToneCloud and tested it with both my 2008 American HSS Strat and my 2021 Gibson SG. I always keep my Spark 40 Output set to 25%, and start with guitar volume an tone settings at 8 (I.e. 80%). I did not adjust the Preset in any way during my test. The...

What guitar and guitar volume and tone setting are you using?

Great! Glad it worked out.

I haven’t tried a bass through my Spark 40; however, if you have a Boost Pedal, you may want to try putting that directly into the Spark Amp-Guitar Chain. Members on the Positive Grid Forum have indicated that the Spark 40 works great with real pedals.

I’d select the imbedded ‘Metal’ Preset in the Spark 40 (left-most knob), and ‘Save as New’ with your own name within the Spark App. Now you can change settings and ‘Overwrite’ to save as you go. I limit ‘Save as New’ to pretty solid, usable sounds. The Spark App has no sorting functionality; so havi...

Have you also posted this on the Positive Grid Forum, “What’s the Big Idea?” Category/Topic? While some PG Forum Members would suggest the staff is occupied elsewhere, this forum category is probably the most direct path to the software/firmware staff for a future ”Wish List”.
