A High-fidelity Mastering One-two Punch

Get to know them!

The Solid State Logic X-ValveComp and Harrison Mastering EQ bundle gives you two highly effective mastering tools: SSL's X-ValveComp and the Harrison Mastering EQ. The SSL X-ValveComp gives you tons of control over your dynamic processing, along with fully adjustable harmonic flavoring that's guaranteed to make your mix really pop. The Harrison Mastering EQ is a 31-band equalizer with loads of powerful features and transparent frequency sculpting that enables you to shape your mix without completely altering its sound. Mastering engineers need top-tier tools, and this bundle arms you with two indispensable plug-ins that you'll want to use on every project.

SSL X-ValveComp

At first glance, the SSL X-ValveComp resembles other workhorse compressors, with all the features you would expect: Threshold, Ratio, Knee, Attack, Release, and Hold controls; sidechain with highpass and lowpass filters; and makeup gain control. However, switch it into valve mode, and it's an entirely different animal, brimming with rich second-order harmonics and creamy vintage flavor. Use the X-ValveComp's Mix knob to operate it in parallel directly on the track you're processing without having to send it to a separate bus, à la New York-style compression — a favorite technique of engineers at Sweetwater. Squash your drums, bass, or vocals for extra heft, and tuck the processed signal underneath the original track to preserve transients and articulation. Full of character and grit, the X-ValveComp is the perfect tool for adding depth and impact to your mix.

Harrison Mastering EQ

The Harrison Mastering EQ is a high-fidelity, 31-band equalizer based on Harrison's XTool plug-in for digital consoles. Loaded with Harrison's revolutionary filter shape for ultra-precise operation, this feature-packed plug-in includes highpass and lowpass filters, a level trim, and momentary bypass controls. You'll appreciate how this plug-in's cutting-edge DSP curve-match yields a flat top across adjacent bands with zero discrete peaks and valleys. You also get an RTA analyzer with Graph and Lightning modes. The Harrison Mastering EQ is the perfect tool for applying a specific tonal balance to a mix without creating drastic changes in its overall sonic character.

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

Offer applies only to single-receipt qualifying purchases. No interest will be charged on the promo balance if you pay it off, in full, within the promo period. If you do not, interest will be charged on the promo balance from the purchase date. The required minimum monthly payments may or may not pay off the promo balance before the end of the promo period, depending on purchase amount, promo length and payment allocation. Regular account terms apply to non-promo purchases and, after promo period ends, to the promo balance. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
