Even if you have no excessive bass problem in your room a preset dialed in with no ir will sound very dull if you then include an ir
Create a new preset while using the ir but even then it won’t be quite as bright and crispy as a non ir sound. To me it is crispy and harsh with no ir high frequencies spike and sizzle too much.
Plat some music you like and are familiar with through the monitors similar to the sound you want your guitar to sound like as a reference and compare as you build your sound in the plugin
